Subject [jira] [Created] (YARN-7938) Yarn task attempt listener bind port range
Date Thu, 15 Feb 2018 18:34:00 GMT
David Johnson created YARN-7938:

             Summary: Yarn task attempt listener bind port range
                 Key: YARN-7938
                 URL: https://issues.apache.org/jira/browse/YARN-7938
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: yarn
    Affects Versions: 2.7.5
            Reporter: David Johnson

Currently, the Yarn task attempt listener binds to a random hight port ".setPort(0)"

For highly locked down environments, this can require a large number of opened ports between
systems, which is troublesome.


I'd recommend either creating a new configuration item, or tying it to the MR_AM_JOB_CLIENT_PORT_RANGE.
