-----------------------------------------
Thanks for the review [~wangda],
bq. we can show it like "<not set>", otherwise it will cause confusion if the
am's nodeLabelExpression = "", but it inherits queue's
defaultNodeLabelExpression.
Actually wanted to discuss with you regarding this, recently while working on
Application Priority, came across that, if the priority for application is not
set in the submission context, then Queue's/cluster max priority is set to the
submission context and also while updating the app they do the same thing. Hope
we could follow the same approach for node labels too. As it would be easy to
analyze. If not other option is to indicate if app label is null, then in the
web ui( also rest? ) show as *<Queue's Default Node Label>*. Also for AM as
*<Application Node Label's Expression>*
bq. show "DEFAULT_PARTITION" when an app's label="", to make it consistent with
queue's page.
Sure, it makes sense but what abt REST ? need to follow the same right ?
bq. QueueCLI#printQueueInfo to print <DEFAULT_PARTITION> when it's ""/null?
OK, will get this done, but should we not support additional CLI similar to the
lines of UI to get the Queue stats based on NodeLabel?
> Expose app/am/queue's node-label-expression to RM web UI / CLI / REST-API
