stack commented on HBASE-4543:
------------------------------
Its working in trunk. I see these messages when I tried it just now:
{code}
2011-11-16 22:20:53,676 DEBUG

> major_compact '.META.' has no effect, although major_compact
> 'any_other_table' works fine from the shell.
> This issue seems to only affect 0.89. The apache-trunk seems to handle this
> case properly.
> The issue is that getTableRegions() in HMaster.java only works if the
> tableName given is a "normal" table.
> The methodology (using a MetaScanner to look through the .META. table for the
> tableName) does not work if
> the tableName is .META.
> The fix modifies getTableRegions() to check if the tableName is .META.; and
> if so, handle it accordingly.
