Description

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

 

com.google.protobuf.InvalidProtocolBufferException: Protocol message was too large.  May be malicious.  Use CodedInputStream.setSizeLimit() to increase the size limit.

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.
