Subject [jira] [Commented] (HBASE-13303) Fix size calculation of results on the region server
Date Thu, 26 Mar 2015 21:23:53 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13303?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14382699#comment-14382699
] 

Andrew Purtell commented on HBASE-13303:
----------------------------------------

bq. Would this be fixed as an addendum here or should I file elsewhere? Or, given that the
point of the addendum to HBASE-11544 is to get rid of NextState, would it be more appropriate
to fix there?

I don't think it really matters. Won't be an issue in 0.98, so we can get a release out on
that line. Not sure about branch-1.0 but there's no release on deck there yet. Whenever we
have a better solution for branch-1+ we should revert this hack anyhow. Would be nice to have
a better solution for branch-1.0 and 0.98 also, then we can revert this hack in those branches
as well.

> One of the problems in the parent is due to different size calculation between client
and server when HFilev3 is used.
> Since tags are _never_ shipped to the client in a scan, we can have special size function
(or a flag on the current one) that does not include the tags and the tags meta information
(the length is what causes the issue), so that client and server will always calculate the
same size.
> I'll make a patch within the hour, unless somebody beats me to it.
> [~apurtell], FYI.
