## What changes were proposed in this pull request?
Several cleanup and improvements for ```spark.logit```:
* ```summary``` should return coefficients matrix, and should output labels for each class if the model is multinomial logistic regression model.
* ```summary``` should not return ```areaUnderROC, roc, pr, ...```, since most of them are DataFrame which are less important for R users. Meanwhile, these metrics ignore instance weights (setting all to 1.0) which will be changed in later Spark version. In case it will introduce breaking changes, we do not expose them currently.
* SparkR test improvement: comparing the training result with native R glmnet.
* Remove argument ```aggregationDepth``` from ```spark.logit```, since it's an expert Param(related with Spark architecture and job execution) that would be used rarely by R users.
## How was this patch tested?
Unit tests.
The ```summary``` output after this change:
multinomial logistic regression:
```
> df <- suppressWarnings(createDataFrame(iris))
> model <- spark.logit(df, Species ~ ., regParam = 0.5)
> summary(model)
$coefficients

Petal_Width 0.000236092 0.4195804 -0.4198165
```
binomial logistic regression:
```

## What changes were proposed in this pull request?
Maven compilation seem to not allow resource is sql/test to be easily referred to in kafka-0-10-sql tests. So moved the kafka-source-offset-version-2.1.0 from sql test resources to kafka-0-10-sql test resources.
## How was this patch tested?
Manually ran maven test

Table
## What changes were proposed in this pull request?
Although, currently, the saveAsTable does not provide an API to save the table as an external table from a DataFrame, we can achieve this functionality by using options on DataFrameWriter where the key for the map is the String: "path" and the value is another String which is the location of the external table itself. This can be provided before the call to saveAsTable is performed.
## How was this patch tested?
Documentation was reviewed for formatting and content after the push was performed on the branch.

when the advertised address is used
## What changes were proposed in this pull request?
In [SPARK-4563](https://issues.apache.org/jira/browse/SPARK-4563) we added the support for the driver to advertise a different hostname/ip (`spark.driver.host` to the executors other than the hostname/ip the driver actually binds to (`spark.driver.bindAddress`). But in the mesos webui's frameworks page, it still shows the driver's binds hostname/ip (though the web ui link is correct). We should fix it to make them consistent.
Before:
![mesos-spark](https://cloud.githubusercontent.com/assets/717363/19835148/4dffc6d4-9eb8-11e6-8999-f80f10e4c3f7.png)
After:
![mesos-spark2](https://cloud.githubusercontent.com/assets/717363/19835149/54596ae4-9eb8-11e6-896c-230426acd1a1.png)
This PR doesn't affect the behavior on the spark side, only makes the display on the mesos master side more consistent.
## How was this patch tested?
Manual test.
- Build the package and build a docker image (spark:2.1-test)
``` sh
./dev/make-distribution.sh -Phadoop-2.6 -Phive -Phive-thriftserver -Pyarn -Pmesos
```
- Then run the spark driver inside a docker container.
``` sh
docker run --rm -it \
--name=spark \
-p 30000-30010:30000-30010 \
-e LIBPROCESS_ADVERTISE_IP=172.17.42.1 \
-e LIBPROCESS_PORT=30000 \
-e MESOS_NATIVE_LIBRARY=/usr/local/lib/libmesos-1.0.0.so \
-e MESOS_NATIVE_JAVA_LIBRARY=/usr/local/lib/libmesos-1.0.0.so \
-e SPARK_HOME=/opt/dist \
spark:2.1-test
```
- Inside the container, launch the spark driver, making use of the advertised address:
``` sh
/opt/dist/bin/spark-shell \
--master mesos://zk://172.17.42.1:2181/mesos \
--conf spark.driver.host=172.17.42.1 \
--conf spark.driver.bindAddress=172.17.0.1 \
--conf spark.driver.port=30001 \
--conf spark.driver.blockManager.port=30002 \
--conf spark.ui.port=30003 \
--conf spark.mesos.coarse=true \
--conf spark.cores.max=2 \
--conf spark.executor.cores=1 \
--conf spark.executor.memory=1g \
--conf spark.mesos.executor.docker.image=spark:2.1-test
```
- Run several spark jobs to ensure everything is running fine.
``` scala
val rdd = sc.textFile("file:///opt/dist/README.md")
rdd.cache().count
```

## What changes were proposed in this pull request?
Currently English stop words list in MLlib contains only the argumented words after removing all the apostrophes, so "wouldn't" become "wouldn" and "t". Yet by default Tokenizer and RegexTokenizer don't split on apostrophes or quotes.
Adding original form to stop words list to match the behavior of Tokenizer and StopwordsRemover. Also remove "won" from list.

Structured Streaming log formats
## What changes were proposed in this pull request?
To be able to restart StreamingQueries across Spark version, we have already made the logs (offset log, file source log, file sink log) use json. We should added tests with actual json files in the Spark such that any incompatible changes in reading the logs is immediately caught. This PR add tests for FileStreamSourceLog, FileStreamSinkLog, and OffsetSeqLog.

committing
## What changes were proposed in this pull request?
It seems some APIs such as `PairRDDFunctions.saveAsHadoopDataset()` do not close the record writer before issuing the commit for the task.
On Windows, the output in the temp directory is being open and output committer tries to rename it from temp directory to the output directory after finishing writing.
So, it fails to move the file. It seems we should close the writer actually before committing the task like the other writers such as `FileFormatWriter`.
Identified failure was as below:
```

## What changes were proposed in this pull request?
Currently Spark answers the `SHOW PARTITIONS` command by fetching all of the table's partition metadata from the external catalog and constructing partition names therefrom. The Hive client has a `getPartitionNames` method which is many times faster for this purpose, with the performance improvement scaling with the number of partitions in a table.
To test the performance impact of this PR, I ran the `SHOW PARTITIONS` command on two Hive tables with large numbers of partitions. One table has ~17,800 partitions, and the other has ~95,000 partitions. For the purposes of this PR, I'll call the former table `table1` and the latter table `table2`. I ran 5 trials for each table with before-and-after versions of this PR. The results are as follows:
Spark at bdc8153, `SHOW PARTITIONS table1`, times in seconds:
7.901
3.983
4.018
4.331
4.261
Spark at bdc8153, `SHOW PARTITIONS table2`
(Timed out after 10 minutes with a `SocketTimeoutException`.)
Spark at this PR, `SHOW PARTITIONS table1`, times in seconds:
3.801
0.449
0.395
0.348
0.336
Spark at this PR, `SHOW PARTITIONS table2`, times in seconds:
5.184
1.63
1.474
1.519
1.41
Taking the best times from each trial, we get a 12x performance improvement for a table with ~17,800 partitions and at least a 426x improvement for a table with ~95,000 partitions. More significantly, the latter command doesn't even complete with the current code in master.
This is actually a patch we've been using in-house at VideoAmp since Spark 1.1. It's made all the difference in the practical usability of our largest tables. Even with tables with about 1,000 partitions there's a performance improvement of about 2-3x.
## How was this patch tested?
I added a unit test to `VersionsSuite` which tests that the Hive client's `getPartitionNames` method returns the correct number of partitions.

integers
## What changes were proposed in this pull request?
DataSet.na.fill(0) used on a DataSet which has a long value column, it will change the original long value.
The reason is that the type of the function fill's param is Double, and the numeric columns are always cast to double(`fillCol[Double](f, value)`) .
```
def fill(value: Double, cols: Seq[String]): DataFrame = {
val columnEquals = df.sparkSession.sessionState.analyzer.resolver
val projections = df.schema.fields.map { f =>
// Only fill if the column is part of the cols list.
if (f.dataType.isInstanceOf[NumericType] && cols.exists(col => columnEquals(f.name, col))) {
fillCol[Double](f, value)
} else {
df.col(f.name)
}
}
df.select(projections : _*)
}
```
For example:
```
scala> val df = Seq[(Long, Long)]((1, 2), (-1, -2), (9123146099426677101L, 9123146560113991650L)).toDF("a", "b")
df: org.apache.spark.sql.DataFrame = [a: bigint, b: bigint]
scala> df.show
+-------------------+-------------------+
| a| b|
+-------------------+-------------------+
| 1| 2|
| -1| -2|
|9123146099426677101|9123146560113991650|
+-------------------+-------------------+
scala> df.na.fill(0).show
+-------------------+-------------------+
| a| b|
+-------------------+-------------------+
| 1| 2|
| -1| -2|
|9123146099426676736|9123146560113991680|
+-------------------+-------------------+
```
the original values changed [which is not we expected result]:
```
9123146099426677101 -> 9123146099426676736
9123146560113991650 -> 9123146560113991680
```

and not auto-generate StreamingQuery.name
## What changes were proposed in this pull request?
Here are the major changes in this PR.
- Added the ability to recover `StreamingQuery.id` from checkpoint location, by writing the id to `checkpointLoc/metadata`.
- Added `StreamingQuery.runId` which is unique for every query started and does not persist across restarts. This is to identify each restart of a query separately (same as earlier behavior of `id`).
- Removed auto-generation of `StreamingQuery.name`. The purpose of name was to have the ability to define an identifier across restarts, but since id is precisely that, there is no need for a auto-generated name. This means name becomes purely cosmetic, and is null by default.
- Added `runId` to `StreamingQueryListener` events and `StreamingQueryProgress`.
Implementation details
- Renamed existing `StreamExecutionMetadata` to `OffsetSeqMetadata`, and moved it to the file `OffsetSeq.scala`, because that is what this metadata is tied to. Also did some refactoring to make the code cleaner (got rid of a lot of `.json` and `.getOrElse("{}")`).
- Added the `id` as the new `StreamMetadata`.
- When a StreamingQuery is created it gets or writes the `StreamMetadata` from `checkpointLoc/metadata`.
- All internal logging in `StreamExecution` uses `(name, id, runId)` instead of just `name`
TODO
- [x] Test handling of name=null in json generation of StreamingQueryProgress
- [x] Test handling of name=null in json generation of StreamingQueryListener events
- [x] Test python API of runId

Python UDFs
## What changes were proposed in this pull request?
As reported in the Jira, there are some weird issues with exploding Python UDFs in SparkSQL.
The following test code can reproduce it. Notice: the following test code is reported to return wrong results in the Jira. However, as I tested on master branch, it causes exception and so can't return any result.
>>> from pyspark.sql.functions import *
>>> from pyspark.sql.types import *
>>>
>>> df = spark.range(10)
>>>
>>> def return_range(value):
... return [(i, str(i)) for i in range(value - 1, value + 1)]
...
>>> range_udf = udf(return_range, ArrayType(StructType([StructField("integer_val", IntegerType()),
... StructField("string_val", StringType())])))
>>>
>>> df.select("id", explode(range_udf(df.id))).show()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/spark/python/pyspark/sql/dataframe.py", line 318, in show
print(self._jdf.showString(n, 20))
File "/spark/python/lib/py4j-0.10.4-src.zip/py4j/java_gateway.py", line 1133, in __call__

File "/spark/python/lib/py4j-0.10.4-src.zip/py4j/protocol.py", line 319, in get_return_value py4j.protocol.Py4JJavaError: An error occurred while calling o126.showString.: java.lang.AssertionError: assertion failed
at scala.Predef$.assert(Predef.scala:156)
at org.apache.spark.sql.execution.CodegenSupport$class.consume(WholeStageCodegenExec.scala:120)
at org.apache.spark.sql.execution.GenerateExec.consume(GenerateExec.scala:57)
The cause of this issue is, in `ExtractPythonUDFs` we insert `BatchEvalPythonExec` to run PythonUDFs in batch. `BatchEvalPythonExec` will add extra outputs (e.g., `pythonUDF0`) to original plan. In above case, the original `Range` only has one output `id`. After `ExtractPythonUDFs`, the added `BatchEvalPythonExec` has two outputs `id` and `pythonUDF0`.
Because the output of `GenerateExec` is given after analysis phase, in above case, it is the combination of `id`, i.e., the output of `Range`, and `col`. But in planning phase, we change `GenerateExec`'s child plan to `BatchEvalPythonExec` with additional output attributes.
It will cause no problem in non wholestage codegen. Because when evaluating the additional attributes are projected out the final output of `GenerateExec`.
However, as `GenerateExec` now supports wholestage codegen, the framework will input all the outputs of the child plan to `GenerateExec`. Then when consuming `GenerateExec`'s output data (i.e., calling `consume`), the number of output attributes is different to the output variables in wholestage codegen.
To solve this issue, this patch only gives the generator's output to `GenerateExec` after analysis phase. `GenerateExec`'s output is the combination of its child plan's output and the generator's output. So when we change `GenerateExec`'s child, its output is still correct.

Added test cases to PySpark.

## What changes were proposed in this pull request?
This is kind of a long-standing bug, it's hidden until https://github.com/apache/spark/pull/15780 , which may add `AssertNotNull` on top of `LambdaVariable` and thus enables subexpression elimination.
However, subexpression elimination will evaluate the common expressions at the beginning, which is invalid for `LambdaVariable`. `LambdaVariable` usually represents loop variable, which can't be evaluated ahead of the loop.
This PR skips expressions containing `LambdaVariable` when doing subexpression elimination.

## What changes were proposed in this pull request?
We currently have function input_file_name to get the path of the input file, but don't have functions to get the block start offset and length. This patch introduces two functions:
1. input_file_block_start: returns the file block start offset, or -1 if not available.
2. input_file_block_length: returns the file block length, or -1 if not available.
## How was this patch tested?
Updated existing test cases in ColumnExpressionSuite that covered input_file_name to also cover the two new functions.

package without Spark
## What changes were proposed in this pull request?
If SparkR is running as a package and it has previously downloaded Spark Jar it should be able to run as before without having to set SPARK_HOME. Basically with this bug the auto install Spark will only work in the first session.
This seems to be a regression on the earlier behavior.
Fix is to always try to install or check for the cached Spark if running in an interactive session.
As discussed before, we should probably only install Spark iff running in an interactive session (R shell, RStudio etc)

## What changes were proposed in this pull request?
Even though in 2.1 creating a partitioned datasource table will not populate the partition data by default (until the user issues MSCK REPAIR TABLE), it seems we still scan the filesystem for no good reason.

## What changes were proposed in this pull request?
This patch significantly improves the IO / file listing performance of schema inference in Spark's built-in CSV data source.
Previously, this data source used the legacy `SparkContext.hadoopFile` and `SparkContext.hadoopRDD` methods to read files during its schema inference step, causing huge file-listing bottlenecks on the driver.
This patch refactors this logic to use Spark SQL's `text` data source to read files during this step. The text data source still performs some unnecessary file listing (since in theory we already have resolved the table prior to schema inference and therefore should be able to scan without performing _any_ extra listing), but that listing is much faster and takes place in parallel. In one production workload operating over tens of thousands of files, this change managed to reduce schema inference time from 7 minutes to 2 minutes.
A similar problem also affects the JSON file format and this patch originally fixed that as well, but I've decided to split that change into a separate patch so as not to conflict with changes in another JSON PR.
## How was this patch tested?
Existing unit tests, plus manual benchmarking on a production workload.

predict should output original label when family = binomial."
## What changes were proposed in this pull request?
It's better we can fix this issue by providing an option ```type``` for users to change the ```predict``` output schema, then they could output probabilities, log-space predictions, or original labels. In order to not involve breaking API change for 2.1, so revert this change firstly and will add it back after [SPARK-18618](https://issues.apache.org/jira/browse/SPARK-18618) resolved.
## How was this patch tested?
Existing unit tests.
This reverts commit daa975f4bfa4f904697bf3365a4be9987032e490.

## What changes were proposed in this pull request?
This fixes the parser rule to match named expressions, which doesn't work for two reasons:
1. The name match is not coerced to a regular expression (missing .r)
2. The surrounding literals are incorrect and attempt to escape a single quote, which is unnecessary
## How was this patch tested?
This adds test cases for named expressions using the bracket syntax, including one with quoted spaces.
