HADOOP-17089: WASB: Update azure-storage-java SDK
Contributed by Thomas Marquardt

DETAILS: WASB depends on the Azure Storage Java SDK. There is a concurrency
bug in the Azure Storage Java SDK that can cause the results of a list blobs
operation to appear empty. This causes the Filesystem listStatus and similar
APIs to return empty results. This has been seen in Spark work loads when jobs
use more than one executor core.

See Azure/azure-storage-java#546 for details on the bug in the Azure Storage SDK.

TESTS: A new test was added to validate the fix. All tests are passing:

wasb:
mvn -T 1C -Dparallel-tests=wasb -Dscale -DtestsThreadCount=8 clean verify
Tests run: 248, Failures: 0, Errors: 0, Skipped: 11
Tests run: 651, Failures: 0, Errors: 0, Skipped: 65

HADOOP-16346. Stabilize S3A OpenSSL support.
Introduces `openssl` as an option for `fs.s3a.ssl.channel.mode`.
The new option is documented and marked as experimental.

For details on how to use this, consult the peformance document
in the s3a documentation.

This patch is the successor to HADOOP-16050 "S3A SSL connections
should use OpenSSL" -which was reverted because of
incompatibilities between the wildfly OpenSSL client and the AWS
HTTPS servers (HADOOP-16347). With the Wildfly release moved up
to 1.0.7.Final (HADOOP-16405) everything should now work.

Related issues:

* HADOOP-15669. ABFS: Improve HTTPS Performance
* HADOOP-16050: S3A SSL connections should use OpenSSL
* HADOOP-16371: Option to disable GCM for SSL connections when running on Java 8
* HADOOP-16405: Upgrade Wildfly Openssl version to 1.0.7.Final

Mate Szalay-Beko 578bd101a6 HADOOP-16765. Fix curator dependencies for gradle projects using hadoop-minicluster. (#1763)
Gradle behaves differently than Maven when processing exclude rules through transitive
dependencies. This causes gradle projects (e.g. in Kudu) that are using Hadoop MiniCluster
to fail because different Guava version come to the classpath through Curator. In this
fix we make sure that ZooKeeper, SLF4J and Gradle gets always excluded from Curator Client
even if they would come through other Curator dependencies transitively.

Mate Szalay-Beko 6d92aa7c30 HADOOP-16579. Upgrade to Curator 4.2.0 and ZooKeeper 3.5.5 (#1656). Contributed by Norbert Kalmár, Mate Szalay-Beko
* HADOOP-16579 - Upgrade to Apache Curator 4.2.0 and ZooKeeper 3.5.5

- Add a static initializer for the unit tests using ZooKeeper to enable
the four-letter-words diagnostic telnet commands. (this is an interface
that become disabled by default, so to keep the ZooKeeper 3.4.x behavior
we enabled it for the tests)
- Also fix ZKFailoverController to look for relevant fail-over ActiveAttempt
records. The new ZooKeeper seems to respond quicker during the fail-over
tests than the ZooKeeper, so we made sure to catch all the relevant records
by adding a new parameter to ZKFailoverontroller.waitForActiveAttempt().

Todd Lipcon 65deb1ac42 HADOOP-16179. hadoop-common pom should not depend on kerb-simplekdc
The hadoop-common pom currently has a dependency on kerb-simplekdc. In
fact, the only classes used from Kerby are in kerb-core and kerb-util
(which is a transitive dependency frmo kerb-core). Depending on
kerb-simplekdc pulls a bunch of other unnecessary classes into the
hadoop-common classpath.

This changes the hadoop-common pom to depend only on kerb-core.

hadoop-minikdc already had the appropriate dependency on kerb-simplekdc
so it continues to pull in what it needs.
