Release Note:Added upgrade script that must be run moving a 0.92.x or 0.94.x era hbase dataset to 0.96.x
Currently, migration works but there's still a couple of rough edges:
HBASE-8045finished 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.
