Summary: Make zkCuratorManager connectionTimeoutMs configurabale
Key: HADOOP-16541
URL: https://issues.apache.org/jira/browse/HADOOP-16541
Project: Hadoop Common
Issue Type: Improvement
Affects Versions: 3.1.0
Reporter: Shen Yinjie
Namenode and resourcemanager do the leader election via curator. Currently
curator's session timeout is defined in CommonConfigurationKeys, but connection
timeout couldn't be changed in hadoop (just use curator's default timeout
hard-coded).
In some scearios, RM can't start since connect to zk timeout. We propose to add
a hadoop configuration for curator's zk connection timeout, so that we can
deal with this situation better.
