Thomas Graves updated SPARK-36772:
----------------------------------
Target Version/s: 3.2.0
> FinalizeShuffleMerge fails with an exception due to attempt id not matching
> ---------------------------------------------------------------------------
>
> Key: SPARK-36772
> URL: https://issues.apache.org/jira/browse/SPARK-36772
> Project: Spark
> Issue Type: Bug
> Components: Shuffle
> Affects Versions: 3.2.0
> Reporter: Mridul Muralidharan
> Priority: Blocker
>
> As part of driver request to external shuffle services (ESS) to finalize the
> merge, it also passes its [application attempt
> id|https://github.com/apache/spark/blob/3f09093a21306b0fbcb132d4c9f285e56ac6b43c/common/network-shuffle/src/main/java/org/apache/spark/network/shuffle/ExternalBlockStoreClient.java#L180]
> so that ESS can validate the request is from the correct attempt.
> This attempt id is fetched from the TransportConf passed in when creating the
> [ExternalBlockStoreClient|https://github.com/apache/spark/blob/67421d80b8935d91b86e8cd3becb211fa2abd54f/core/src/main/scala/org/apache/spark/SparkEnv.scala#L352]
> - and the transport conf leverages a [cloned
> copy|https://github.com/apache/spark/blob/0494dc90af48ce7da0625485a4dc6917a244d580/core/src/main/scala/org/apache/spark/network/netty/SparkTransportConf.scala#L47]
> of the SparkConf passed to it.
> Application attempt id is set as part of SparkContext
> [initialization|https://github.com/apache/spark/blob/67421d80b8935d91b86e8cd3becb211fa2abd54f/core/src/main/scala/org/apache/spark/SparkContext.scala#L586].
> But this happens after driver SparkEnv has [already been
> created|https://github.com/apache/spark/blob/67421d80b8935d91b86e8cd3becb211fa2abd54f/core/src/main/scala/org/apache/spark/SparkContext.scala#L460].
> Hence the attempt id that ExternalBlockStoreClient uses will always end up
> being -1 : which will not match the attempt id at ESS (which is based on
> spark.app.attempt.id) : resulting in merge finalization to always fail ("
> java.lang.IllegalArgumentException: The attempt id -1 in this
> FinalizeShuffleMerge message does not match with the current attempt id 1
> stored in shuffle service for application ...")
