[jira] Commented: (HBASE-424) Should be able to enable/disable
.META. table
Posted by "Jim Kellerman (JIRA)" <ji...@apache.org>.

Jim Kellerman commented on HBASE-424:
-------------------------------------
Only the -ROOT- table cannot be disabled. IMO, if the root table needs to be modified, it should be done off-line.
However, I see no restrictions on offlining the .META. table

-------------------------------------
Why can't we do this? Is it a shell problem or a HBase region server problem or what?

Jim Kellerman resolved HBASE-424.
---------------------------------
Resolution: Fixed
Enable table was waiting for the META region to come on-line. That doesn't work if you're trying to enable the META table.
Committed.

stack commented on HBASE-424:
-----------------------------
Try the shell. Will throw an exception. Will help figure where the problem if any is. Run 'disable ".META."'. Maybe its a non-issue now?
