[jira] [Commented] (HBASE-5293) Purge hfile v1 from code base

    [ https://issues.apache.org/jira/browse/HBASE-5293?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13194858#comment-13194858 ] 

Todd Lipcon commented on HBASE-5293:
------------------------------------

I'm against doing this in 0.94 until we have some other patch where maintaining v1 is a substantial pain. If we release 0.94 fairly soon, I think many people will want to upgrade from 0.90, and going through an intermediate version is a pain.

> If we do this though, as Matt Corgan suggests up on mailing list, we will need to make sure all hfile v1s in an hbase.rootdir have been compacted out of existence.  We'll probably need to bump the hbase.version to indicate the check for hfile v1s has been run.  A migration script will need to be run that checks the hbase.rootdir for hfile v1s and runs a major compaction if any found.
> I've not put a version on this issue.
