--------------------------------------
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.
