[jira] [Updated] (MAPREDUCE-7054) Configurable task attempt
listener bind port range
[ https://issues.apache.org/jira/browse/MAPREDUCE-7054?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jason Lowe updated MAPREDUCE-7054:
----------------------------------
Summary: Configurable task attempt listener bind port range (was: Yarn task attempt listener bind port range)
Moved this to the MAPREDUCE project since this is specific to the MapReduce ApplicationMaster behavior.
> Configurable task attempt listener bind port range
> --------------------------------------------------
>
> 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.
