Miles Crawford updated YARN-5039:
---------------------------------
Attachment: capacity-scheduler-at-debug.log.gz
Attached capacity-scheduler-at-debug.log.gz, which has a few minutes of DEBUG
level for the whole package right at the end of the log.
The stuck application is 0033, and there are three nodes with 100GB or more
memory listed as available in the resource manager UI.

> Often when we submit applications to an incompletely utilized cluster, they
> sit, unable to start for no apparent reason.
> There are multiple nodes in the cluster with available resources, but the
> resourcemanger logs show that scheduling is being skipped. The scheduling is
> skipped because the application itself has reserved the node? I'm not sure
> how to interpret this log output:
