I am also facing the same issue. but My server hard disk is new. There is no warning/alert in my Ambari level.
Once my current job completes, then only the second job is allowed to execute..
If my first job is running for 60 minutes, my second job is on hold. Any suggestions.
server capacity : 16 core , 64 GB RAM
Hi, this Looks like fifo-scheduling / capacity scheduling with 1 group only Try to switch to fair scheduling in yarn.
