Allen Wittenauer commented on YARN-3484:
----------------------------------------
I won't get a chance to look at this (or any other non-bug bash related
patches) until Friday. Please do not commit it yet. I really don't want to
open another jira to fix this again. Thanks.

> We need to do some work on yarn top's shell code.
> a) Just checking for TERM isn't good enough. We really need to check the
> return on tput, especially since the output will not be a number but an error
> string which will likely blow up the java code in horrible ways.
> b) All the single bracket tests should be double brackets to force the bash
> built-in.
> c) I'd think I'd rather see the shell portion in a function since it's rather
> large. This will allow for args, etc, to get local'ized and clean up the
> case statement.
