Description

HMaster does not restart when rsgroup is enabled and /hbase/WALs is moved

HMaster restarts properly if rsgroup is not enabled even if /hbase/WALs is moved.

Steps to reproduce:

1. start the cluster
2. create a table do some put, delete
3. kill all the region servers and master
4. move WALs directory for backup (-mv /hbase/WALs /hbase/WALs2)
5. start the cluster
6. Master start fails, initialization keep failing
