2014-03-07 17:32:33,802 WARN org.apache.hadoop.hbase.util.FSTableDescriptors: The following folder is in HBase's root directory and doesn't contain a table descriptor, do consider deleting it: recovered.edits

-----

Manually deleting the recover.edits will solve the Exception being printed.

In hbase-trx, it is necessary to find the significance of the recovered.edits directory and what can be done to make it compatible with the current version of HBase.

Initial thoughts would be to rename it to '.recovered.edits' or to delete the directory if it is no longer used

I have a fix for this, the code change will check the new name for an old log directory vs the recovered_edits. Will check into seatrans_2 when branch is stabilized:

+import org.apache.hadoop.hbase.HConstants;
...

- Path oldLogDir = new Path(getRootDir(), HLogSplitter.RECOVERED_EDITS);
+ // Directory used in newer version
+ // Path oldLogDir = new Path(getRootDir(), HLogSplitter.RECOVERED_EDITS);
+ Path oldLogDir = new Path(getRootDir(), HConstants.HREGION_OLDLOGDIR_NAME);

Changed directory name to /hbase/.oldlogs vs /hbase/recovered.edits
