Subject [jira] [Commented] (HBASE-5293) Purge hfile v1 from code base
Date Mon, 30 Jan 2012 08:35:11 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5293?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13195989#comment-13195989
] 

Nicolas Spiegelberg commented on HBASE-5293:
--------------------------------------------

+1 on adding a script to check for V1 HFiles & running a major compact on any Stores that
do
-1 on deprecating HFileV1 in code anytime soon.  wasn't it just recently that people were
still running 0.20?

> 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.
