             Summary: DUCC SM Service debug support
                 Key: UIMA-3734
                 URL: https://issues.apache.org/jira/browse/UIMA-3734
             Project: UIMA
          Issue Type: Improvement
          Components: DUCC
            Reporter: Jim Challenger
            Assignee: Jim Challenger


DUCC SM should support process_debug <port>.

Proposed implementation: on registration the process_debug <port> option is 
allowed.  The cli inserts a process_debug_host as well so the remote process 
knows which host to connect to.

When set, SM prohibits expansion beyond a single process.  DuccServiceSubmit 
uses process_debug and process_debug_host to set the JVM args so the process 
can  call-home to a java debugger waiting on the indicated port.

ducc_service modify allows dynamic set / reset of debug; changing the state 
requires manual stop and restart of the service.
