    • Incompatible change, Reviewed
    • Non-HA rollback steps have been changed. Run the rollback command on the namenode (`bin/hdfs namenode -rollback`) before starting cluster with '-rollback' option using (sbin/start-dfs.sh -rollback).

    Description

      In HA while performing rollback , we use “hdfs namenode –rollback” which would prompt user for confirmation. ( Implemented as part of HDFS-5138)

      For Non-HA , as per doc if we perform rollback using “start-dfs.sh –rollback” , then namenode startup hangs ( As it tries to start namenode in daemon mode , hence will not be able to prompt user for confirmation )
