Date Sat, 27 Aug 2016 01:09:21 GMT
Andrew Wang created YARN-5570:
---------------------------------

             Summary: NodeManager blocks kill attempts during startup if ResourceManager is
down
                 Key: YARN-5570
                 URL: https://issues.apache.org/jira/browse/YARN-5570
             Project: Hadoop YARN
          Issue Type: Bug
    Affects Versions: 2.7.3
            Reporter: Andrew Wang


Found while testing a 2.7.3 RC:

{quote}
* If you start the NodeManager and not the RM, the NM has a handler for SIGTERM and SIGINT
that blocked my Ctrl-C and kill attempts during startup. I had to kill -9 it.

[~stevel@apache.org] tells me that this is potentially addressed by YARN-679, though that's
a large patch.
