-----------------------------------
Summary: DUCC: JP scaleout not derived from process_pipeline_count
for DD jobs
Key: UIMA-5142
URL: https://issues.apache.org/jira/browse/UIMA-5142
Project: UIMA
Issue Type: Bug
Components: DUCC
Reporter: Jerry Cwiklik
Assignee: Jerry Cwiklik
Fix For: 2.1.0-Ducc
For DD based jobs the scaleout is not based on process_pipeline_count specified
in job's spec. Instead, the code tries to fetch the scaleout from a DD which is
not right.
When a job is submitted, the OR creates a command line to launch a JP to run
the job. The OR takes the value of process_pipeline_count parameter and creates
a System property from it as follows:
arg[4]: -Dducc.deploy.JpThreadCount=2
All the JP needs to do is to fetch the property value and use it to create
matching number of process threads that will request WIs from a JD.
