Prasanth Jayachandran commented on HIVE-15217:
----------------------------------------------
I will add another option that waits/watches until RUNNING (or any state) state.
The problem with keeping shorter refresh interval is with the way we are
viewing the output. Currently the output is printed as json which is only
machine readable. The output that gets printed is way too much even for 10s of
nodes. IMO we should change the output format to something like tez job monitor
and update in-place but that's a broader change and optionally output json. I
think both formats will be useful. Refreshing too often and spitting json out
is completely unreadable. Thoughts?

> There is few seconds overhead for launching the llap status command. To avoid
> we can add "watch" mode to llap status tool that refreshes the status after
> configured interval.
