We are still experiencing periodic problems with applications hanging when a number of jobs are submitted in parallel.  We have reduced 'maxRunningApps', increased the virtual core count, and also increased 'oozie.service.callablequeueservice.threads' to 40.  In many cases, the applications do not hang, however this is not consistent.   Regarding YARN issue number 1913 (https://issues.apache.org/jira/browse/YARN-1913), is this patch incorporated in CDH 5.1.0, the version we are using?  YARN-1913 indicates the affected version is 2.3.0, and is fixed in 2.5.0.  Our Hadoop version in 5.1.0 is 2.3.0.   Thank you,   Michael Reynolds   ...
