Subject [jira] [Commented] (HBASE-19092) Make Tag IA.LimitedPrivate and expose for CPs
Date Mon, 20 Nov 2017 06:05:01 GMT

    [ https://issues.apache.org/jira/browse/HBASE-19092?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16258835#comment-16258835

stack commented on HBASE-19092:
-------------------------------

[~anoop.hbase] says

bq.  This will look as a bad design IMHO.

... if CPs have to cast Cell to ExtendedCell if they want to pull Tags from a Cell.

I agree.

But it is late in the game. So, we ok allowing that getting Tags from Cell is a little messy
in hbase2? That said, we want Tags integral to Cell, not apart as they have been, so getting
Tags from Cell/ExtendedCell is where we want to be; its just not clean in hbase2. I think
we can live w/ that (needs good doc).

> We need to make tags as LimitedPrivate as some use cases are trying to use tags like
timeline server. The same topic was discussed in dev@ and also in HBASE-18995.
> Shall we target this for beta1 - cc [~saint.ack@gmail.com].
> So once we do this all related Util methods and APIs should also move to LimitedPrivate
Util classes.
