https://community.cloudera.com/t5/Support-Questions/Spark-jobs-are-stuck-under-YARN-Fair-Scheduler/m-p/287349#M213001 <P>Hi&nbsp;<a href="https://community.cloudera.com/t5/user/viewprofilepage/user-id/72245">@ssk26</a>&nbsp;<BR /><BR />From my perspictive you are limiting your default queue to use at minimum 1024MB 0vCores and at maximum 8196MB 0vCores. In both cases no cores are set - when you try to run a job it requires to run with 1024MB memory and 1vCores - it then fails to allocate the 1vCore due to 0vCore min/max restriction and it sends 'exceeds maximum AM resources allowed'&nbsp;</P><P>&nbsp;</P><P>That's why I think the issue is with the core utilization and not with memory.&nbsp;<BR /><BR /></P><P>HTH<BR /><BR />Best,<BR />Lyubomir</P> Fri, 10 Jan 2020 11:54:13 GMT lyubomirangelo 2020-01-10T11:54:13Z
