> ViewFileSystem.close doesn't close child filesystems and causes FileSystem
> objects leak.
> ----------------------------------------------------------------------------------------
>
> Key: HADOOP-15565
> URL: https://issues.apache.org/jira/browse/HADOOP-15565
> Project: Hadoop Common
> Issue Type: Bug
> Reporter: Jinglun
> Priority: Major
> Attachments: HADOOP-15565.0001.patch
>
>
> When we create a ViewFileSystem, all it's child filesystems will be cached by
> FileSystem.CACHE. Unless we close these child filesystems, they will stay in
> FileSystem.CACHE forever.
> I think we should let FileSystem.CACHE cache ViewFileSystem only, and let
> ViewFileSystem cache all it's child filesystems. So we can close
> ViewFileSystem without leak and won't affect other ViewFileSystems.
> I find this problem because i need to re-login my kerberos and renew
> ViewFileSystem periodically. Because FileSystem.CACHE.Key is based on
> UserGroupInformation, which changes everytime i re-login, I can't use the
> cached child filesystems when i new a ViewFileSystem. And because
> ViewFileSystem.close does nothing but remove itself from cache, i leak all
> it's child filesystems in cache.
