-------------------------------------
Assignee: Steve Loughran
> PathOutputCommitters to work with dynamic partition overwrite
> -------------------------------------------------------------
>
> 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
> Assignee: 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.
