> 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.
