See https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/46896/testReport/(root)/KinesisStreamTests/test_kinesis_stream/ Because Streaming Python didn’t work when merging https://github.com/apache/spark/pull/9403, the PR build didn’t report the Python test failure actually.

| | | | | | | | | | | | | | | | | | | | Currently pivot's signature looks like ```scala scala.annotation.varargs def pivot(pivotColumn: Column, values: Column*): GroupedData scala.annotation.varargs def pivot(pivotColumn: String, values: Any*): GroupedData ``` I think we can remove the one that takes "Column" types, since callers should always be passing in literals. It'd also be more clear if the values are not varargs, but rather Seq or java.util.List. I also made similar changes for Python.

| | | | | | | | | | | | | reduceByKeyAndWindow invFunc is optional and can be None. Instead of invFunc (the parameter) invReduceFunc (a local function) was checked for trueness (that is, not None, in this context). A local function is never None, thus the case of invFunc=None (a common one when inverse reduction is not defined) was treated incorrectly, resulting in loss of data. In addition, the docstring used wrong parameter names, also fixed. Author: David Tolpin <david.tolpin@gmail.com> Closes #9775 from dtolpin/master.

* [SPARK-11740][STREAMING] Fix the race condition of two checkpoints in a batchShixiong Zhu2015-11-171-5/+4
| | | | | | | | We will do checkpoint when generating a batch and completing a batch. When the processing time of a batch is greater than the batch interval, checkpointing for completing an old batch may run after checkpointing for generating a new batch. If this happens, checkpoint of an old batch actually has the latest information, so we want to recovery from it. This PR will use the latest checkpoint time as the file name, so that we can always recovery from the latest checkpoint file.

| | | | | | | | | | | | | | | | | | | | | | | | This patch adds the following options to the JSON data source, for dealing with non-standard JSON files: * `allowComments` (default `false`): ignores Java/C++ style comment in JSON records * `allowUnquotedFieldNames` (default `false`): allows unquoted JSON field names * `allowSingleQuotes` (default `true`): allows single quotes in addition to double quotes * `allowNumericLeadingZeros` (default `false`): allows leading zeros in numbers (e.g. 00012) To avoid passing a lot of options throughout the json package, I introduced a new JSONOptions case class to define all JSON config options. Also updated documentation to explain these options.

| | | | | | | | | | | | | | | | | | | | | For now they are thin wrappers around the corresponding Hive UDAFs. One limitation with these in Hive 0.13.0 is they only support aggregating primitive types. I chose snake_case here instead of camelCase because it seems to be used in the majority of the multi-word fns. Do we also want to add these to `functions.py`?

| | | | | | | | | | | | | Could jkbradley and davies review it? - Create a wrapper class: `LDAModelWrapper` for `LDAModel`. Because we can't deal with the return value of`describeTopics` in Scala from pyspark directly. `Array[(Array[Int], Array[Double])]` is too complicated to convert it. - Add `loadLDAModel` in `PythonMLlibAPI`.
