             Summary: PathOutputCommitters to work with dynamic partition overwrite -if they support it
                 Key: SPARK-40034
                 URL: https://issues.apache.org/jira/browse/SPARK-40034
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core, SQL
    Affects Versions: 3.4.0
            Reporter: Steve Loughran


sibling of MAPREDUCE-7403: allow PathOutputCommitter implementation to declare that they support the semantics required by spark dynamic partitioning:

* rename to work as expected
* working dir to be on same fs as final dir

They will do this through implementing StreamCapabilities and adding a new probe, "mapreduce.job.committer.dynamic.partitioning" ; the spark side changes are to
* postpone rejection of dynamic partition overwrite until the output committer is created
* allow it if the committer implements StreamCapabilities and returns true for {{hasCapability("mapreduce.job.committer.dynamic.partitioning")))

this isn't going to be supported by the s3a committers, they don't meet the requirements. The manifest committer of MAPREDUCE-7341 running against abfs and gcs does work.
