5092ea62ec HADOOP-13230. S3A to optionally retain directory markers. 
This adds an option to disable "empty directory" marker deletion,
so avoid throttling and other scale problems.

This feature is *not* backwards compatible.
Consult the documentation and use with care.

HADOOP-17196. Fix C/C++ standard warnings (#2208) 
* Passing C/C++ standard flags -std is
  not cross-compiler friendly as not all
  compilers support all values.
* Thus, we need to make use of the
  appropriate flags provided by CMake in
  order to specify the C/C++ standards.

Improving router's performance for delegation tokens related operations. It achieves the goal by removing watchers from router on tokens since based on our experience. The huge number of watches inside Zookeeper is degrading Zookeeper's performance pretty hard. The current limit is about 1.2-1.5 million.

HADOOP-16986. S3A to not need wildfly on the classpath. (#1948) 
HADOOP-16986. S3A to not need wildfly JAR on its classpath.

Contributed by Steve Loughran

This is a successor to HADOOP-16346, which enabled the S3A connector
to load the native openssl SSL libraries for better HTTPS performance.

That patch required wildfly.jar to be on the classpath. This
update:

* Makes wildfly.jar optional except in the special case that 
"fs.s3a.ssl.channel.mode" is set to "openssl"

* Retains the declaration of wildfly.jar as a compile-time
dependency in the hadoop-aws POM. This means that unless
explicitly excluded, applications importing that published
maven artifact will, transitively, add the specified
wildfly JAR into their classpath for compilation/testing/
distribution.

This is done for packaging and to offer that optional
speedup. It is not mandatory: applications importing
the hadoop-aws POM can exclude it if they choose.

HADOOP-16898. Batch listing of multiple directories via an (unstable) interface 
Contributed by Steve Loughran.

This moves the new API of HDFS-13616 into a interface which is implemented by
HDFS RPC filesystem client (not WebHDFS or any other connector)

This new interface, BatchListingOperations, is in hadoop-common,
so applications do not need to be compiled with HDFS on the classpath.
They must cast the FS into the interface.

instanceof can probe the client for having the new interface -the patch
also adds a new path capability to probe for this.

The FileSystem implementation is cut; tests updated as appropriate.

All new interfaces/classes/constants are marked as @unstable.

HADOOP-14630 Contract Tests to verify create, mkdirs and rename under a file is forbidden 
Contributed by Steve Loughran.

Not all stores do complete validation here; in particular the S3A
Connector does not: checking up the entire directory tree to see if a path matches
is a file significantly slows things down.

This check does take place in S3A mkdirs(), which walks backwards up the list of
parent paths until it finds a directory (success) or a file (failure).
In practice production applications invariably create destination directories
before writing 1+ file into them -restricting check purely to the mkdirs()
call deliver significant speed up while implicitly including the checks.

HADOOP-16885. Fix hadoop-commons TestCopy failure 
Followup to HADOOP-16885: Encryption zone file copy failure leaks a temp file

Moving the delete() call broke a mocking test, which slipped through the review process.

HADOOP-16885. Encryption zone file copy failure leaks a temp file 
Contributed by Xiaoyu Yao.

Contains HDFS-14892. Close the output stream if createWrappedOutputStream() fails

Copying file through the FsShell command into an HDFS encryption zone where
the caller lacks permissions is leaks a temp ._COPYING file
and potentially a wrapped stream unclosed.

This is a convergence of a fix for S3 meeting an issue in HDFS.

S3: a HEAD against a file can cache a 404, 
 -you must not do any existence checks, including deleteOnExit(),
  until the file is written. 

Hence: HADOOP-16490, only register files for deletion the create worked
and the upload is not direct. 

HDFS-14892. HDFS doesn't close wrapped streams when IOEs are raised on
create() failures. Which means that an entry is retained on the NN.
-you need to register a file with deleteOnExit() even if the file wasn't
created.

This patch:

* Moves the deleteOnExit to ensure the created file get deleted cleanly.
* Fixes HDFS to close the wrapped stream on failures.
