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

             Summary: YARN NodeManager directories when passes as comma separated directories
- agent create a single directory including comma.
                 Key: AMBARI-2868
                 URL: https://issues.apache.org/jira/browse/AMBARI-2868
             Project: Ambari
          Issue Type: Bug
          Components: agent
    Affects Versions: 1.4.0
            Reporter: Siddharth Wagle
            Assignee: Siddharth Wagle
             Fix For: 1.4.0
         Attachments: AMBARI-2868.patch

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.
