Ted Yu updated HBASE-19338:
---------------------------
Attachment: 19338.master.003.patch
Patch v3 fixes the similar call in VisibilityUtils and AccessController since
they are on hot path.
Lijin's patches didn't carry header. So the format stays the same.
Whoever commits the final patch, please give Lijin credit.
