Erik Krogen updated HADOOP-14169:
---------------------------------
Attachment: HADOOP-14169.000.patch
Attaching v0 patch with a very simple fix to implement
{{listStatusIterator}}/{{listLocatedStatus}} on {{ChRootedFs}} and
{{listStatusIterator}} on {{ViewFs}}. Minor refactor in {{ViewFs}} for code
sharing between {{listStatusIterator}} and {{listLocatedStatus}}.
[~jira.shegalov], [~cnauroth], pinging based on previous involvement with the
similar work in HADOOP-11812 - are either of you interested in reviewing?
> Implement listStatusIterator, listLocatedStatus for ViewFs

> Key: HADOOP-14169

> Project: Hadoop Common

>
> Similar to what HADOOP-11812 did for ViewFileSystem, currently ViewFs does
> not respect optimizations to {{listStatusIterator}} or {{listLocatedStatus}},
> using the naive implementations within {{AbstractFileSystem}}. This can cause
> performance issues if iterating over a large directory, especially if the
> locations are also needed. This can be easily fixed.
