[jira] [Created] (HBASE-4543) major_compact '.META.' has no effect
major_compact '.META.' has no effect
------------------------------------
Key: HBASE-4543
URL: https://issues.apache.org/jira/browse/HBASE-4543
Project: HBase
Issue Type: Bug
Reporter: Amitanand Aiyer
Priority: Minor
major_compact '.META.' has no effect, although major_compact 'any_other_table' works fine from the shell.
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.

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.
