I think it's sufficient to check the Accumulo version (Constants.VERSION) major.minor. We don't need to use the data version in here at all. The protocol version is the version of the RPC protocol... the data version is the version of the data persisted in ZK and HDFS... and the Accumulo version is the overall version of the software. Only the RPC protocol version and the Accumulo version are relevant here. -- This is an automated message from the Apache Git Service.
