Victor Xu updated HBASE-9781:
-----------------------------

    Status: Patch Available  (was: Open)

So I add some code to delete the temporary directory before throwing the exception.

> Each time I use HRegion.merge(HRegion a, HRegion b) method to merge two regions, it makes crazy that there would always be some temporary directories left on hdfs because of merging's "Files have same sequenceid" exceptions. I have to clean them by hand.
