Description

This is the parent ticket. We plan to backport the upgrade from trunk to branch-3.3 in 3 PRs:
PR1(HADOOP-18515). Cherry pick https://github.com/apache/hadoop/pull/3241 which simply bump the version.

PR2(HADOOP-18519). Cherry pick https://github.com/apache/hadoop/pull/3266 which solved the deprecation of PathChildrenCache/TreeCache in new ZK. Note, we need to backport https://issues.apache.org/jira/browse/HDFS-15383 along because PR-3266 is based on this earlier change, specifically isTokenWatcherEnabled was introduced in ZKDelegationTokenSecretManager.java

PR3(HADOOP-18520).Cherry pick https://github.com/apache/hadoop/pull/4812 which solved the deprecation of EnsurePath in new Curator. Note, as this change contained a bug, fixed by https://github.com/apache/hadoop/pull/4885 , we thus need to cherry pick this bug fix PR as well.
