Hello,   I have CDH 5.16.2 with HBase 1.2.0 and a new Cluster with CDH 6.2.0 with HBase 2.1.0. I would like to use CopyTable to copy data into the new cluster. The containers give an error: ERROR [main] org.apache.hadoop.hbase.client.AsyncProcess: Failed to get region location org.apache.hadoop.hbase.exceptions.UnknownProtocolException: org.apache.hadoop.hbase.exceptions.UnknownProtocolException: Is this a pre-hbase-1.0.0 or asynchbase client?
