Varun Vasudev commented on YARN-4232:
-------------------------------------
[~bibinchundatt] - couple of points -
1)
HTTPS doesn't imply kerberos - you should keep the logic for the two
different. Use hadoop.http.authentication.type to figure out the type of web
security
2)
The current patch can't handle custom authentication filters. For custom auth
filters, we probably want to skip getting the uptime.

> *Steps to reproduce*
> Start Top command in YARN in HA mode
> ./yarn top
> {noformat}
> usage: yarn top

> + Enter
> -queues <arg> Comma separated list of queues to restrict applications
> -rows <arg> Number of rows on the terminal
> -types <arg> Comma separated list of types to restrict applications,
> case sensitive(though the display is lower case)
> -users <arg> Comma separated list of users to restrict applications
> {noformat}
