> 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)
>       writeFile at /home/xieliang/infra/hbase/target/hbase-0.94.3-mdh1.0.0-SNAPSHOT/hbase-0.94.3-mdh1.0.0-SNAPSHOT/bin/region_mover.rb:283
>   unloadRegions at /home/xieliang/infra/hbase/target/hbase-0.94.3-mdh1.0.0-SNAPSHOT/hbase-0.94.3-mdh1.0.0-SNAPSHOT/bin/region_mover.rb:354
>          (root) at /home/xieliang/infra/hbase/target/hbase-0.94.3-mdh1.0.0-SNAPSHOT/hbase-0.94.3-mdh1.0.0-SNAPSHOT/bin/region_mover.rb:480
> 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.
