Jerry Cwiklik closed UIMA-5048.
-------------------------------
Resolution: Fixed
When a command line is missing the PM logs a message to identify if this is due
to communication error or the OR sending an invalid cmd line. The publishes the
process map to agents which marks a job with no cmdline as Failed with
reason=MissingCommandLine
> DUCC Orchestrator (OR) record Process Manager (PM) Job CommandLine requests

> Issue Type: Bug
> Components: DUCC
> Reporter: Lou DeGenaro
> Assignee: Jerry Cwiklik
> 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 Processes from launching, since there is no
> command line
> 3. Increase PM's -Xmx on uima-ducc-demo from 150M to 200M (same as SM and WS)
