      Description

      I am facing this problem while testing HBASE-8348(migration).
      ->I have started two clusters with 0.94 version to replicate data from one cluster to other. When we have started master,writing cluster id without PB.
      -> killed both the clusters when Replication in progress
      -> running migration script to migrate hdfs and zk data to 0.96.0(No changes in cluster id.)
      -> starting 0.96.0 processes.
      Then not able to start region server.

      java.io.IOException: Region server startup failed
