    Affects Versions: 2.0.0, 1.1.0
            Reporter: Ashish Singhi
            Priority: Critical

Default value for {{hbase.rpc.client.impl}} is set to AsyncRpcClient.
When trying to install HBase with Kerberos, RegionServer is not working functionally.
The following log is logged in its log file

When set hbase.rpc.client.impl to RpcClientImpl, there seems to be no issue.
