> Improve file listing for ViewFileSystem
> ---------------------------------------
>
> Key: SPARK-31047
> URL: https://issues.apache.org/jira/browse/SPARK-31047
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.1.0
> Reporter: Manu Zhang
> Assignee: Manu Zhang
> Priority: Minor
>
> https://issues.apache.org/jira/browse/SPARK-27801 has improved file listing
> for DistributedFileSystem, where {{InMemoryFileIndex.listLeafFiles}} makes
> use of DistributedFileSystem's one single {{listLocatedStatus}} to namenode.
> This ticket intends to improve the case where ViewFileSystem is used to
> manage multiple DistributedFileSystems. It has also overridden the
> {{listLocatedStatus}} method by delegating to the filesystem it resolves to,
> e.g. DistributedFileSystem.
