[SPARK-4169] [Core] Accommodate non-English Locales in unit tests

For me the core tests failed because there are two locale dependent parts in the code.
Look at the Jira ticket for details.

Why is it necessary to check the exception message in isBindCollision in
https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/util/Utils.scala#L1686
?

SPARK-2548 [STREAMING] JavaRecoverableWordCount is missing

Here's my attempt to re-port `RecoverableNetworkWordCount` to Java, following the example of its Scala and Java siblings. I fixed a few minor doc/formatting issues along the way I believe.

PR #3175 is for master branch only and can't be backported to branch 1.1 directly because Hive 0.13.1 support.

[SPARK-3971][SQL] Backport #2843 to branch-1.1

This PR backports #2843 to branch-1.1. The key difference is that this one doesn't support Hive 0.13.1 and thus always returns `0.12.0` when `spark.sql.hive.version` is queried.

6 other commits on which #2843 depends were also backported, they are:

- #2887 for `SessionState` lifecycle control
- #2675, #2823 & #3060 for major test suite refactoring and bug fixes
- #2164, for Parquet test suites updates
- #2493, for reading `spark.sql.*` configurations

[SPARK-3954][Streaming] Optimization to FileInputDStream

about convert files to RDDS there are 3 loops with files sequence in spark source.
loops files sequence:
1.files.map(...)
2.files.zip(fileRDDs)
3.files-size.foreach
It's will very time consuming when lots of files.So I do the following correction:
3 loops with files sequence => only one loop

[SPARK-3495][SPARK-3496] Backporting block replication fixes made in master to branch 1.1

The original PR was #2366

This backport was non-trivial because Spark 1.1 uses ConnectionManager instead of NioBlockTransferService, which required slight modification to unit tests. Other than that the code is exactly same as in the original PR. Please refer to discussion in the original PR if you have any thoughts.
