[jira] [Updated] (HBASE-4543) major_compact '.META.' has no effect

     [ https://issues.apache.org/jira/browse/HBASE-4543?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Amitanand Aiyer updated HBASE-4543:
-----------------------------------

          Description: 
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.
