...r.
Constructor of `org.apache.spark.executor.Executor` should not set context class loader of current thread, which is backend Actor's thread.
Run the following code in local-mode REPL.
```
scala> case class Foo(i: Int)
scala> val ret = sc.parallelize((1 to 100).map(Foo), 10).collect
```
This causes errors as follows:
```

This is because the class loaders to deserialize result `Foo` instances might be different from backend Actor's, and the Actor's class loader should be the same as Driver's.

via Maven build
I am observing build failures when the Maven build reaches tests in the new SQL components. (I'm on Java 7 / OSX 10.9). The failure is the usual complaint from scala, that it's out of permgen space, or that JIT out of code cache space.
I see that various build scripts increase these both for SBT. This change simply adds these settings to scalatest's arguments. Works for me and seems a bit more consistent.
(I also snuck in cures for new build warnings from new scaladoc. Felt too trivial for a new PR, although it's separate. Just something I also saw while examining the build output.)

This is just a slight variation on https://github.com/apache/spark/pull/234 and alternative suggestion for SPARK-1325. `scala-actors` is not necessary. `SparkBuild.scala` should be updated to reflect the direct dependency on `scala-reflect` and `scala-compiler`. And the `repl` build, which has the same dependencies, should also be consistent between Maven / SBT.

BoundedPriorityQueue based implementation
Also updated the documentation for top and takeOrdered.
On my simple test of sorting 100 million (Int, Int) tuples using Spark, Guava's top k implementation (in Ordering) is much faster than the BoundedPriorityQueue implementation for roughly sorted input (10 - 20X faster), and still faster for purely random input (2 - 5X).

(This follows from a side point on SPARK-1133, in discussion of the PR: https://github.com/apache/spark/pull/164 )
Commons IO is barely used in the project, and can easily be replaced with equivalent calls to Guava or the existing Spark `Utils.scala` class.
Removing a dependency feels good, and this one in particular can get a little problematic since Hadoop uses it too.

Various spark scripts load spark-env.sh. This can cause growth of any variables that may be appended to (SPARK_CLASSPATH, SPARK_REPL_OPTS) and it makes the precedence order for options specified in spark-env.sh less clear.
One use-case for the latter is that we want to set options from the command-line of spark-shell, but these options will be overridden by subsequent loading of spark-env.sh. If we were to load the spark-env.sh first and then set our command-line options, we could guarantee correct precedence order.
Note that we use SPARK_CONF_DIR if available to support the sbin/ scripts, which always set this variable from sbin/spark-config.sh. Otherwise, we default to the ../conf/ as usual.

This removes duplicated logic, dead code and casting when planning parquet table scans and hive table scans.
Other changes:
- Fix tests now that we are doing a better job of column pruning (i.e., since pruning predicates are applied before we even start scanning tuples, columns required by these predicates do not need to be included in the output of the scan unless they are also included in the final output of this logical plan fragment).
- Add rule to simplify trivial filters. This was required to avoid `WHERE false` from getting pushed into table scans, since `HiveTableScan` (reasonably) refuses to apply partition pruning predicates to non-partitioned tables.

This adds some changes on top of the initial work by @scrapcodes in #20:
The goal here is to do automated checking of Spark commits to determine whether they break binary compatibility.
1. Special case for inner classes of package-private objects.
2. Made tools classes accessible when running `spark-class`.
3. Made some declared types in MLLib more general.
4. Various other improvements to exclude-generation script.
5. In-code documentation.

Fixing this bug required the following:
- Creation of a new logical node that converts a schema to lowercase.
- Generalization of the subquery eliding rule to also elide this new node
- Fixing of several places where too tight assumptions were made on the types of `InsertIntoTable` children.
- I also removed an API that was left in by accident that exposed catalyst data structures, and fix the logic that pushes down filters into hive tables scans to correctly compare attribute references.

Continue our discussions from https://github.com/apache/incubator-spark/pull/575
This PR is WIP because it depends on a SNAPSHOT version of breeze.
Per previous discussions and benchmarks, I switched to breeze for linear algebra operations. @dlwh and I made some improvements to breeze to keep its performance comparable to the bare-bone implementation, including norm computation and squared distance. This is why this PR needs to depend on a SNAPSHOT version of breeze.
@fommil , please find the notice of using netlib-core in `NOTICE`. This is following Apache's instructions on appropriate labeling.
I'm going to update this PR to include:
1. Fast distance computation: using `\|a\|_2^2 + \|b\|_2^2 - 2 a^T b` when it doesn't introduce too much numerical error. The squared norms are pre-computed. Otherwise, computing the distance between the center (dense) and a point (possibly sparse) always takes O(n) time.
2. Some numbers about the performance.
3. A released version of breeze. @dlwh, a minor release of breeze will help this PR get merged early. Do you mind sharing breeze's release plan? Thanks!

`SimpleDateFormat` is not thread-safe. Some places use the same SimpleDateFormat object without safeguard in the multiple threads. It will cause that the Web UI displays improper date.
This PR creates a new `SimpleDateFormat` every time when it's necessary. Another solution is using `ThreadLocal` to store a `SimpleDateFormat` in each thread. If this PR impacts the performance, I can change to the latter one.

This PR removes our test dependence on files hosted at Berkeley by checking the test queries and answers into the repository. This should also fix the maven Jenkins build.
I realize this is a *giant* commit. But size wise its actually pretty small. We are only looking at ~1.2Mb compressed (~30Mb uncompressed). Given that we already have a ~80Mb file permanently added to the spark code lineage, I do not think that this will change the developer experience significantly.
Furthermore, I think it is good engineering practice to consider such test support files as "code", since changes to them would indicate a change in functionality. These files were only excluded from the initial PR as I wanted the diff to be readable.

Sorry! I added this test at the last minute and failed to run it in maven as well.
Note that, this will probably not be sufficient to actually fix the maven jenkins build, as that does not use the dev/run-tests scripts. We will need to configure it to also run dev/download-hive-tests.sh. The other option would be to check in the tests as I suggested in the original PR. (I can do this if we agree its the right thing to do).
Long term it would probably be a good idea to also have maven run some sort of test env setup script so that we can decouple the test environment from the jenkins configuration.

This pull request adds support to Spark for working with structured data using a simple SQL dialect, HiveQL and a Scala Query DSL.
*This is being contributed as a new __alpha component__ to Spark and does not modify Spark core or other components.*
The code is broken into three primary components:
- Catalyst (sql/catalyst) - An implementation-agnostic framework for manipulating trees of relational operators and expressions.
- Execution (sql/core) - A query planner / execution engine for translating Catalyst’s logical query plans into Spark RDDs. This component also includes a new public interface, SqlContext, that allows users to execute SQL or structured scala queries against existing RDDs and Parquet files.
- Hive Metastore Support (sql/hive) - An extension of SqlContext called HiveContext that allows users to write queries using a subset of HiveQL and access data from a Hive Metastore using Hive SerDes. There are also wrappers that allows users to run queries that include Hive UDFs, UDAFs, and UDTFs.
A more complete design of this new component can be found in [the associated JIRA](https://spark-project.atlassian.net/browse/SPARK-1251).
[An updated version of the Spark documentation, including API Docs for all three sub-components,](http://people.apache.org/~pwendell/catalyst-docs/sql-programming-guide.html) is also available for review.
With this PR comes support for inferring the schema of existing RDDs that contain case classes. Using this information, developers can now express structured queries that are automatically compiled into RDD operations.
```scala
// Define the schema using a case class.
case class Person(name: String, age: Int)
val people: RDD[Person] =
sc.textFile("people.txt").map(_.split(",")).map(p => Person(p(0), p(1).toInt))
// The following is the same as 'SELECT name FROM people WHERE age >= 10 && age <= 19'
val teenagers = people.where('age >= 10).where('age <= 19).select('name).toRdd
```
RDDs can also be registered as Tables, allowing SQL queries to be written over them.
```scala
people.registerAsTable("people")
val teenagers = sql("SELECT name FROM people WHERE age >= 10 && age <= 19")
```
The results of queries are themselves RDDs and support standard RDD operations:
```scala
teenagers.map(t => "Name: " + t(0)).collect().foreach(println)
```
Finally, with the optional Hive support, users can read and write data located in existing Apache Hive deployments using HiveQL.
```scala
sql("CREATE TABLE IF NOT EXISTS src (key INT, value STRING)")
sql("LOAD DATA LOCAL INPATH 'src/main/resources/kv1.txt' INTO TABLE src")
// Queries are expressed in HiveQL
sql("SELECT key, value FROM src").collect().foreach(println)
```
## Relationship to Shark
Unlike Shark, Spark SQL does not act as a drop in replacement for Hive or the HiveServer. Instead this new feature is intended to make it easier for Spark developers to run queries over structured data, using either SQL or the query DSL. After this sub-project graduates from Alpha status it will likely become a new optimizer/backend for the Shark project.

This is a bug fix for #42 (79d07d66040f206708e14de393ab0b80020ed96a).
In Master, we do not bind() each SparkUI because we do not want to start a server for each finished application. However, when we remove the associated application, we call stop() on the SparkUI, which throws an assertion failure.
This fix ensures we don't call stop() on a SparkUI that was never bind()'ed.
Author: Andrew Or <andrewor14@gmail.com>
Closes #188 from andrewor14/ui-fix and squashes the following commits:

# Principal Component Analysis
Computes the top k principal component coefficients for the m-by-n data matrix X. Rows of X correspond to observations and columns correspond to variables. The coefficient matrix is n-by-k. Each column of the coefficients return matrix contains coefficients for one principal component, and the columns are in descending order of component variance. This function centers the data and uses the singular value decomposition (SVD) algorithm.
## Testing
Tests included:
* All principal components
* Only top k principal components
* Dense SVD tests
* Dense/sparse matrix tests
The results are tested against MATLAB's pca: http://www.mathworks.com/help/stats/pca.html
## Documentation
Added to mllib-guide.md
## Example Usage
Added to examples directory under SparkPCA.scala

This is for JIRA:https://spark-project.atlassian.net/browse/SPARK-1099
And this is what I do in this patch (also commented in the JIRA) @aarondav
This is really a behavioral change, so I do this with great caution, and welcome any review advice:
1 I change the "MASTER=local" pattern of create LocalBackEnd . In the past, we passed 1 core to it . now it use a default cores
The reason here is that when someone use spark-shell to start local mode , Repl will use this "MASTER=local" pattern as default.
So if one also specify cores in the spark-shell command line, it will all go in here. So here pass 1 core is not suitalbe reponding to our change here.
2 In the LocalBackEnd , the "totalCores" variable are fetched following a different rule(in the past it just take in a userd passed cores, like 1 in "MASTER=local" pattern, 2 in "MASTER=local[2]" pattern"
rules:
a The second argument of LocalBackEnd 's constructor indicating cores have a default value which is Int.MaxValue. If user didn't pass it , its first default value is Int.MaxValue
b In getMaxCores, we first compare the former value to Int.MaxValue. if it's not equal, we think that user has passed their desired value, so just use it
c. If b is not satified, we then get cores from spark.cores.max, and we get real logical cores from Runtime. And if cores specified by spark.cores.max is bigger than logical cores, we use logical cores, otherwise we use spark.cores.max
3 In SparkContextSchedulerCreationSuite 's test("local") case, assertion is modified from 1 to logical cores, because "MASTER=local" pattern use default vaules.

731aefa [qqsun8819] 1 LocalBackend not change 2 In SparkContext do some process to the cores and pass it to original LocalBackend constructor

The fleeting nature of the Spark Web UI has long been a problem reported by many users: The existing Web UI disappears as soon as the associated application terminates. This is because SparkUI is tightly coupled with SparkContext, and cannot be instantiated independently from it. To solve this, some state must be saved to persistent storage while the application is still running.
The approach taken by this PR involves persisting the UI state through SparkListenerEvents. This requires a major refactor of the SparkListener interface because existing events (1) maintain deep references, making de/serialization is difficult, and (2) do not encode all the information displayed on the UI. In this design, each existing listener for the UI (e.g. ExecutorsListener) maintains state that can be fully constructed from SparkListenerEvents. This state is then supplied to the parent UI (e.g. ExecutorsUI), which renders the associated page(s) on demand.
This PR introduces two important classes: the **EventLoggingListener**, and the **ReplayListenerBus**. In a live application, SparkUI registers an EventLoggingListener with the SparkContext in addition to the existing listeners. Over the course of the application, this listener serializes and logs all events to persisted storage. Then, after the application has finished, the SparkUI can be revived by replaying all the logged events to the existing UI listeners through the ReplayListenerBus.
This feature is currently integrated with the Master Web UI, which optionally rebuilds a SparkUI from event logs as soon as the corresponding application finishes.
More details can be found in the commit messages, comments within the code, and the [design doc](https://spark-project.atlassian.net/secure/attachment/12900/PersistingSparkWebUI.pdf). Comments and feedback are most welcome.

In implicit ALS computation, the user or product factor is used twice in each iteration. Caching can certainly help accelerate the computation. I saw the running time decreased by ~70% for implicit ALS on the movielens data.
I also made the following changes:
1. Change `YtYb` type from `Broadcast[Option[DoubleMatrix]]` to `Option[Broadcast[DoubleMatrix]]`, so we don't need to broadcast None in explicit computation.
2. Mark methods `computeYtY`, `unblockFactors`, `updateBlock`, and `updateFeatures private`. Users do not need those methods.
3. Materialize the final matrix factors before returning the model. It allows us to clean up other cached RDDs before returning the model. I do not have a better solution here, so I use `RDD.count()`.
