             Summary: Backport HDFS-15383 and HADOOP-17835 to branch-3.3
                 Key: HADOOP-18519
                 URL: https://issues.apache.org/jira/browse/HADOOP-18519
             Project: Hadoop Common
          Issue Type: Improvement
    Affects Versions: 3.3.5
            Reporter: Melissa You
            Assignee: Melissa You


This is a sub-task of HADOOP-18518 to upgrade zk&curator on 3.3 branches.

It contains clean cherry pick from [https://github.com/apache/hadoop/pull/3266] which solved the deprecation of PathChildrenCache/TreeCache in new ZK. 
Also clean cherry pick from https://issues.apache.org/jira/browse/HDFS-15383 because PR-3266 is based on this earlier change, specifically isTokenWatcherEnabled was introduced in [ZKDelegationTokenSecretManager.java|https://github.com/apache/hadoop/pull/2047/files#diff-f65a8ac81e253e85af159ba041fbad62fbb34b5bd909c1e9fc93d58222f406b9]
