>             Project: Ambari
>          Issue Type: Bug
>            Reporter: Andrew Onischuk
>            Assignee: Andrew Onischuk
>             Fix For: 2.1.0
>
>
> PROBLEM: When restarting the NodeManager via Ambari, the Ambari agent conducts
> a recursive chown on the YARN local cache configuration directory.
> Something like this: chown -R yarn:hadoop /hadoop/yarn/local
> I have seen this in Ambari 2.0 and Ambari 2.0.1 - where 2.0.1 was upgraded
> from 2.0
> BUSINESS IMPACT: The problem is that user directories exist under
> /hadoop/yarn/local/usercache/<username> and subsequent containers will not
> have rights to the user's directory after the NM restart, in a secure cluster.
> STEPS TO REPRODUCE: N/A
> SUPPORT ANALYSIS: As seen in the Ambari logs for starting the NM:
>     
>     
>     u"Directory['/hadoop/yarn/local']" {'group': 'hadoop', 'recursive': True, 
>     'cd_access': 'a', 'ignore_failures': True, 'mode': 0775, 'owner': 'yarn¹} 
>
