Hi, I remember having a similar issue. My job was demanding for more memory then available in the cluster, that’s why it was waiting forever.
Could you check the resource-/nodemanager logs? Also the „Scheduler" page in the Webapp might give a hint whether the job is not starting because of unsufficient resources. Cheers Seb.
