Bugs: AMBARI-9372
    https://issues.apache.org/jira/browse/AMBARI-9372


Repository: ambari


Description
-------

The NodeManager fails on hosts in multi-host cluster with the following: 
```
Fail: Execution of 'chown -R ambari-qa /hadoop/yarn/local/usercache/ambari-qa' returned 1.
chown: cannot access `/hadoop/yarn/local/usercache/ambari-qa': No such file or directory
```

Solution, chech existance of `/hadoop/yarn/local/usercache/ambari-qa` before attempting to
`chown`
