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. 
   
   ![image](https://user-images.githubusercontent.com/2844826/159257471-4398ae11-fad3-4aee-8f56-1b89bef2f611.png)
   
   
   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.
