> Extend add-opens flag to container launch commands on JDK17 nodes
> -----------------------------------------------------------------
>
> Key: MAPREDUCE-7456
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-7456
> Project: Hadoop Map/Reduce
> Issue Type: New Feature
> Affects Versions: 3.4.0
> Reporter: Peter Szucs
> Assignee: Peter Szucs
> Priority: Major
> Labels: pull-request-available
>
> There was a previous ticket for adding add-opens flag to container launch to
> be able to run them on JDK17 nodes:
> https://issues.apache.org/jira/browse/MAPREDUCE-7449
> As testing discovered, this should be extended with
> "{_}-add-exports=java.base/sun.net.dns=ALL-UNNAMED{_}" and
> "{_}-add-exports=java.base/sun.net.util=ALL-UNNAMED{_}" options to be able to
> run containers on Isilon.
