[jira] [Created] (HDFS-5152) Avoiding redundant Kerberos login for Zookeeper client in ActiveStandbyElector

Kai Zheng created HDFS-5152:
-------------------------------

             Summary: Avoiding redundant Kerberos login for Zookeeper client in ActiveStandbyElector
                 Key: HDFS-5152
                 URL: https://issues.apache.org/jira/browse/HDFS-5152
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: security
            Reporter: Kai Zheng


Based on the fix in HADOOP-8315, it's possible to deploy a secured HA cluster with SASL support for connection with Zookeeper. However it requires extra configuration for JAAS to initialize the Zookeeper client because the client will do another login in it even when ZKFC service actually has already passed the Kerberos login during its starting.
