>             Project: Spark
>          Issue Type: Improvement
>          Components: Spark Core, SQL
>    Affects Versions: 3.4.0
>            Reporter: Steve Loughran
>            Priority: Minor

> 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.
