Hi,
I installed ranger hbase plugin in Hbase-0.99.2.
When i restart hbase after applying plugin, it is giving below error in
hbase region-server logs:

After some retires HBase master goes down.
The error is coming due to permissions of hbase system table: namespace.
Please let me know how can I resolve this issue ?
