---------------------------------------

[~swagle] can you please check if this is an issue with other directories? RM/NM/NN/Journal Nodes/others just to be sure we dont think this in other places?

> Looks like here is what happens:
> {code}
> $nm_local_dirs = hdp_default("yarn-site/yarn.nodemanager.local-dirs", "$hadoop_tmp_dir/nm-local-dir")
> {code}
> This code takes in the nm local directories as comman separated files, but its never split around the comma's.
> When using multiple directories for  NodeManager local directories here is what I saw on NM:
> {code}
> root@ip-10-80-149-186 yarn]# pwd
> /grid/0/hadoop/yarn,/grid/1/hadoop/yarn
> {code}
> A directory with a comma was created. This causes NM to go unhealthy which causes the jobs to fail - and all.
