> when i worked at a shared/common box with my colleague, found this error while moving
region:
> NativeException: java.io.FileNotFoundException: /tmp/hh-hadoop-srv-st01.bj (Permission
denied)

> 2013-11-07 15:08:12 Unload host hh-hadoop-srv-st01.bj failed.
> The root cause is currently getFilename in region move script will get the same output
with diff users. One possible quick fix is just add the username to the filename.
