Xuan Gong commented on YARN-71:
-------------------------------

Test the patch in a single cluster running at Centos 6:
1. config LinuxContainerExecutor
2. start namenode,datanode,resourcemanager,nodemanager
3. run a pi example
4. manually kill the nodemanager
5. found the localFiles under localDir which need to be deleted
6. restart nodemanager
7. verify the localFiles have been deleted.

> We have to make sure that NodeManagers cleanup their local files on restart.
> It may already be working like that in which case we should have tests validating this.
