Zheng Hu commented on HBASE-22621:
----------------------------------
All checksytle is related to the DirectBuffer API which will be removed in
future release, but we still need it to clean the memory of DirectByteBuffer.
So plan to keep it here. Another issue is TestExportSnapshotNoCluster, run
serveral times under my host, it worked OK.
Will plan to commit this big patch to branch-2 if no objections. Thanks.
