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.
