Marcelo Vanzin commented on SPARK-25766:
----------------------------------------
That code doesn't exist anymore in 2.4... there could be a similar issue in
{{HadoopFSDelegationTokenProvider}}, though.
> AMCredentialRenewer can leak FS clients
> ---------------------------------------
>
> Key: SPARK-25766
> URL: https://issues.apache.org/jira/browse/SPARK-25766
> Project: Spark
> Issue Type: Bug
> Components: YARN
> Affects Versions: 2.4.0
> Reporter: Steve Loughran
> Priority: Trivial
>
> AMCredentialRenewer's scheduled {{writeNewCredentialsToHDFS}} operation
> creates a new FS connector each time, so as to access the store with
> refreshed credentials
> but it doesn't close it after, so any resources used by the client are kept
> around. This is more expensive with the cloud store connectors which create
> thread pools.
> It should call {{remoteFs.close()}} at the end of its work.
