             Summary: Add a new ClusterMetrics.Option SERVERS_NAME to only return the live region servers's name without metrics
                 Key: HBASE-21938
                 URL: https://issues.apache.org/jira/browse/HBASE-21938
             Project: HBase
          Issue Type: Bug
            Reporter: Guanghao Zhang


One of our production cluster ( which has 200000 regions) meet one protobuf exception when getClusterStatus.

 
{code:java}
com.google.protobuf.InvalidProtocolBufferException: Protocol message was too large.  May be malicious.  Use CodedInputStream.setSizeLimit() to increase the size limit.
{code}
And there are some client methods which call getClusterStatus but only need server names. Plan to add a new option which only to return server name. So we can reduce the influence scope even we meet this problem.
