Subject [jira] [Updated] (MAPREDUCE-7054) Configurable task attempt listener bind port range
Date Thu, 15 Feb 2018 20:27:00 GMT

     [ 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.

>                 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.
