Bibin A Chundatt commented on YARN-3989:
----------------------------------------

[~sunilg] and [~Naganarasimha]

Currently only NodeLabel i would like to put in scope for this Jira.Other commands makes it more complicated. 
Few commands as [~sunilg]  pointed out.

# addToCluserNodeLabels
# removeFromClusterNodeLabels
# replaceLabelsOnNode

Its a huge stack trace which is shown in console and from trace it becomes very difficult to get the actual error message.Most of the cases only direct messages are intended for users not full stack trace.

So as of now will define scope only to Nodelabel commands in this jira.

> Currently for nodelabel command execution failure  full exception stacktrace is shown. This jira is to handle exceptions and show only messages.

> As I see it, I can see full exception stack trace in client side in this case (also in case of other commands too) and its too verbose. I think we can make its compact and n it will be more easily readable.
