----------------------------------
Summary: DUCC Orchestrator (OR) record Process Manager (PM) Job
CommandLine requests
Key: UIMA-5048
URL: https://issues.apache.org/jira/browse/UIMA-5048
Project: UIMA
Issue Type: Bug
Components: DUCC
Reporter: Lou DeGenaro
Assignee: Lou DeGenaro
Fix For: 2.2.0-Ducc
On uima-ducc-demo we saw one Job that caused PM to OOM. According to the PM
log, the request for Job 784 from PM to Orchestrator to fetch the CommandLine
(comprising the CLASSPATH) resulted in the unexpected value of null.
1. Put more logging code into OR to better understand why a null value was
returned to PM
2. PM should prevent such Jobs from launching
3. Increase PM's -Xmx on uima-ducc-demo from 150M to 200M (same as SM and WS)
