Himanshu Vashishtha updated HBASE-8348:
---------------------------------------
Attachment: HBASE-8348-approach-2-v2.2.patch
Attaching patch which does:
a) correctly set fs (using hbase.rootdir uri).
b) minor refactoring in UpgradeTo96 (initially, we were checking for live
processes even if user doesn't set execute option).
Rest of the patch is similar to old one. Thanks.
> Polish the migration to 0.96

> Currently, migration works but there's still a couple of rough edges:
> - HBASE-8045 finished the .META. migration but didn't remove ROOT, so it's
> still on the filesystem.
> - Data in ZK needs to be removed manually. Either we fix up the data in ZK
> or we delete it ourselves.
> - TestMetaMigrationRemovingHTD has a testMetaUpdatedFlagInROOT method, but
> ROOT is gone now.
> Elliott was also mentioning that we could have "hbase migrate" do the HFileV1
> checks, clear ZK, remove ROOT, etc.
