Subject [jira] [Created] (UIMA-6100) viaducc does not handle attach_console correctly
Date Wed, 24 Jul 2019 22:00:00 GMT
Eddie Epstein created UIMA-6100:

             Summary: viaducc does not handle attach_console correctly
                 Key: UIMA-6100
                 URL: https://issues.apache.org/jira/browse/UIMA-6100
             Project: UIMA
          Issue Type: Bug
          Components: DUCC
            Reporter: Eddie Epstein
            Assignee: Eddie Epstein
             Fix For: 3.0.1-Ducc

by default viaducc enable both attach_console and cancel_on_interrupt. An option was added
to suppress cancel_on_interrupt with the intent to let the remote process continue running
after the local submit process was terminated. This was misguided because in many cases the
remote process will terminate when it's stdout/stderr pipes were broken.

The new change makes attach_console an option, which in addition sets cancel_on_interrupt.
The result is that by default viaducc will only monitor the DUCC state of the remote process
and the remote process will not be terminated if the local submitter is stopped.
