This is required in addition to the odd no of ZK we already configured. Sharing the Apache [doc](https://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-hdfs/HDFSHighAvailabilityWithQJM.html#Automatic_Failover) in-case it helps. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
