maybe u can check the logs from port 8088 on your browser. that was RM
UI. just choose your job id and then check the logs.

Hi
It could be because of many of reasons. Also I am not sure about
which scheduler your are using, pls share more details such as RM
log etc.
I could point out few reasons
- Such as "Not enough resource is cluster" can cause this
- If using Capacity Scheduler, if queue capacity is maxed out,
such case can happen.
- Similarly if max-am-resource-percent is crossed per queue
level, then also AM container may not be launched.
you could check RM log to get more information if AM container is
laucnhed.
Thanks
Sunil
