> Key: SPARK-33230
> URL: https://issues.apache.org/jira/browse/SPARK-33230
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.4.7, 3.0.1
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Major
> Fix For: 3.1.0, 3.0.2, 2.4.8

>
> The Hadoop S3A staging committer has problems with >1 spark sql query being launched simultaneously, as it uses the jobID for its path in the clusterFS to pass the commit information from tasks to job committer.
> If two queries are launched in the same second, they conflict and the output of job 1 includes that of all job2 files written so far; job 2 will fail with FNFE.
> Proposed:
> job conf to set {{"spark.sql.sources.writeJobUUID"}} to the value of {{WriteJobDescription.uuid}}
> That was the property name which used to serve this purpose; any committers already written which use this property will pick it up without needing any changes.
