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.
