> Key: MAPREDUCE-7054
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-7054
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Components: mr-am
> Affects Versions: 2.7.5
> Reporter: David Johnson
> Priority: Minor
>
> 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.
