      Description

      Looks like when using distcp diff options between two snapshots from a hadoop 3 cluster to hadoop 2 cluster , we get below exception and seems to be break backward compatibility due to new API introduction getSnapshotDiffReportListing.

       

      hadoop distcp -diff s1 s2 -update src_cluster_path dst_cluster_path
      org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.ipc.RpcNoSuchMethodException): Unknown method getSnapshotDiffReportListing called on org.apache.hadoop.hdfs.protocol.ClientProtocol protocol
