[jira] [Created] (UIMA-5048) DUCC Orchestrator (OR) record Process Manager (PM) Job CommandLine requests

Lou DeGenaro created UIMA-5048:
----------------------------------

             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)
