Eli Collins resolved HDFS-422.
------------------------------
Resolution: Duplicate
> fuse-dfs leaks FileSystem handles as it never disconnects them because the
> FileSystem.Cache does not do reference counting
> --------------------------------------------------------------------------------------------------------------------------
>
> Key: HDFS-422
> URL: https://issues.apache.org/jira/browse/HDFS-422
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: contrib/fuse-dfs
> Reporter: Pete Wyckoff
> Priority: Minor
>
> since users may be doing multiple file operations at the same time, a single
> task in fuse, can never call close() on a filesystem (ie
> libhdfs::hdfsDisconnect) because there may be another thread for the same
> user.
> as such, either fuse-dfs needs to do reference counting or FileSystem.Cache
> needs to or maybe enable a mode where one can turn off the Cache??
> I currently am not seeing any problems in production, but I am still running
> 0.18 version which keeps only one connection as root.
