liubingxing opened a new pull request #4088: URL: https://github.com/apache/hadoop/pull/4088
JIRA: [HDFS-16514](https://issues.apache.org/jira/browse/HDFS-16514) Recently, we used the [Standby Read] feature in our test cluster, and deployed 4 namenode as follow: node1 -> active nn node2 -> standby nn node3 -> observer nn node3 -> observer nn If we set ’dfs.client.failover.random.order=true‘, the client may failover twice and wait a long time to send msync to active namenode.  I think we can reduce the sleep time of the first several failover based on the number of namenode. For example, if 4 namenode are configured, the sleep time of first three failover operations is set to zero. -- This is an automated message from the Apache Git Service.
