Weiwei Yang commented on YARN-7779:
-----------------------------------
Thanks [~asuresh], [~sunilg] for the comments.
{quote}Can you also add a testcase in TestRMWebServices
{quote}
I am adding a test case and will include that in next patch.
{quote} Else that column will be too wider.
{quote}
That's true, but I think we should be fine in 1st version giving we are not
expecting too many tags. We can have more improvements as you mentioned in
feature. Right now, get them displayed on UI will help us debugging issues and
play with allocation tags.
{quote}Also this could be added new UI as well.
{quote}
Once the feature branch gets merged to trunk, we can open a Jira to display
tags in new UI.
Thanks
