Tsuyoshi OZAWA commented on YARN-2147:
--------------------------------------

[~airbots], thank you for taking this JIRA. 

One minor nits from me: Should we add spaces before and after the {{!=}} and before {{(}}?

{code}
+        if(credentials!=null) {
{code}

Otherwise changes looks good to me.

> When an client submits an application and the delegation token process fails the client
can lack critical details needed to understand the nature of the error.  Only the message
of the error exception is conveyed to the client, which sometimes isn't enough to debug.
