Jonathan Hsieh commented on HBASE-12054:
----------------------------------------
great, thanks. +1.
Can you add a release note about which tablenames used to have migration
problems before this fix?
Maybe something like:
Prior to HBase 0.98.7, if you have 0.94 tables named data, archive, corrupt,
lib, WALs, splitWAl, or oldWALs upgrading would fail.
> bad state after NamespaceUpgrade with reserved table names

> If 94 has a table called "data" NamespaceUpgrade will fail to bring that
> table up and the generated layout will be dirty with stuff like
> "/hbase/data/.data" and so on.
> (the reserved names that we have no longer apply in 96+ since the data is
> separate from the root dir)
