Because `sql/hive`'s tests depend on the test jar of `sql/core`, we do not need to store `SQLTestUtils` and `ParquetTest` in `src/main`. We should only add stuff that will be needed by `sql/console` or Python tests (for Python, we need it in `src/main`, right? davies).

Following the discussion in http://apache-spark-developers-list.1001551.n3.nabble.com/python-converter-in-HBaseConverter-scala-spark-examples-td10001.html. I made some modification in three files in package examples:
1. HBaseConverters.scala: the new converter will converts all the records in an hbase results into a single string
2. hbase_input.py: as the value string may contain several records, we can use ast package to convert the string into dict
3. HBaseTest.scala: as the package examples use hbase 0.98.7 the original constructor HTableDescriptor is deprecated. The updation to new constructor is made

My experiments with scheduling very short tasks in standalone cluster mode indicated that a significant amount of time was being spent in scheduling the tasks (>500ms for 256 tasks). I found that most of the time was being spent in creating a new instance of serializer for each task. Changing this to just one serializer brought down the scheduling time to 8ms.

The previous PR for SPARK-7224 (#5790) broke JDK 6, because it used java.nio.Path, which was in jdk 7, and not in 6. This PR uses Guava's `Files` to handle directory creation, and etc...
The description from the previous PR:
> This patch contains an `IvyTestUtils` file, which dynamically generates jars and pom files to test the `--packages` feature without having to rely on the internet, and Maven Central.
cc pwendell
I also rand the flaky test about 20 times locally, it didn't fail a single time, but I think it may fail like once every 100 builds? I still haven't figured the cause yet, but the test before it, `--jars` was also failing after we turned off the `--packages` test in `SparkSubmitSuite`. It may be related to the launch of SparkSubmit.

KinesisReceiver calls worker.run() which is a blocking call (while loop) as per source code of kinesis-client library - https://github.com/awslabs/amazon-kinesis-client/blob/v1.2.1/src/main/java/com/amazonaws/services/kinesis/clientlibrary/lib/worker/Worker.java.
This results in infinite loop while calling sparkStreamingContext.stop(stopSparkContext = false, stopGracefully = true) perhaps because ReceiverTracker is never able to register the receiver (it's receiverInfo field is a empty map) causing it to be stuck in infinite loop while waiting for running flag to be set to false.

When initializing `executionHive`, we only masks
`javax.jdo.option.ConnectionURL` to override metastore location. However,
other properties that relates to the actual Hive metastore data source are not
masked. For example, when using Spark SQL with a PostgreSQL backed Hive
metastore, `executionHive` actually tries to use settings read from
`hive-site.xml`, which talks about PostgreSQL, to connect to the temporary
Derby metastore, thus causes error.
To fix this, we need to mask all metastore data source properties.
Specifically, according to the code of [Hive `ObjectStore.getDataSourceProps()`
method] [1], all properties whose name mentions "jdo" and "datanucleus" must be
included.
[1]: https://github.com/apache/hive/blob/release-0.13.1/metastore/src/java/org/apache/hadoop/hive/metastore/ObjectStore.java#L288
Have tested using postgre sql as metastore, it worked fine.

SPARK-3386 / #5606 modified the shuffle write path to re-use serializer instances across multiple calls to DiskBlockObjectWriter. It turns out that this introduced a very rare bug when using `KryoSerializer`: if auto-reset is disabled and reference-tracking is enabled, then we'll end up re-using the same serializer instance to write multiple output streams without calling `reset()` between write calls, which can lead to cases where objects in one file may contain references to objects that are in previous files, causing errors during deserialization.
This patch fixes this bug by calling `reset()` at the start of `serialize()` and `serializeStream()`. I also added a regression test which demonstrates that this problem only occurs when auto-reset is disabled and reference-tracking is enabled.

This PR updates `HashingTF` to output ML attributes that tell the number of features in the output column. We need to expand `UnaryTransformer` to support output metadata. A `df outputMetadata: Metadata` is not sufficient because the metadata may also depends on the input data. Though this is not true for `HashingTF`, I think it is reasonable to update `UnaryTransformer` in a separate PR. `checkParams` is added to verify common requirements for params. I will send a separate PR to use it in other test suites. jkbradley

This is because the Spark's shutdown hook stops the context, and the streaming jobs fail in the middle. The correct solution is to stop the streaming context before the spark context. This PR adds the shutdown hook to do so with a priority higher than the SparkContext's shutdown hooks priority.

7a7876b [Holden Karau] Add a startTime property to match the corresponding one in the Scala SparkContext
Having a SQLContext singleton would make it easier for applications to use a lazily instantiated single shared instance of SQLContext when needed. It would avoid problems like
1. In REPL/notebook environment, rerunning the line {{val sqlContext = new SQLContext}} multiple times created different contexts while overriding the reference to previous context, leading to issues like registered temp tables going missing.
2. In Streaming, creating SQLContext directly leads to serialization/deserialization issues when attempting to recover from DStream checkpoints. See [SPARK-6770]. Also to get around this problem I had to suggest creating a singleton instance - https://github.com/apache/spark/blob/master/examples/src/main/scala/org/apache/spark/examples/streaming/SqlNetworkWordCount.scala
This can be solved by {{SQLContext.getOrCreate}} which get or creates a new singleton instance of SQLContext using either a given SparkContext or a given SparkConf.
