Enis Soztutar commented on HBASE-13428:
---------------------------------------
TableStates in meta is one thing. Reverted from branch-1 for now. I think a
previous patch also changes the table descriptor format in the hdfs which was
causing hbase master to not work with data already in hdfs (not sure whether
that was undone).
