Anoop Sam John commented on HBASE-14730:
----------------------------------------
With HFile V3, writing Tags to files will happen. It can be turned off using
that boolean state in HFileContext. But this is not exposed for user
modification. The code handles that when it see that there are no tags as part
of any of the Cells in new File. Places where turning ON this context state
(It should be ON by default) is a bug for us. I mean the ImportTSV case etc.
This jira speaks abt end user usage of tag related attributes for data and V3
is not enabled. So there is no problem in the fix.
> region server needs to log warnings when there are attributes configured for
> cells with hfile v2
