[jira] [Created] (HDFS-3513) HttpFS should cache filesystems

Alejandro Abdelnur created HDFS-3513:
----------------------------------------

             Summary: HttpFS should cache filesystems
                 Key: HDFS-3513
                 URL: https://issues.apache.org/jira/browse/HDFS-3513
             Project: Hadoop HDFS
          Issue Type: Improvement
    Affects Versions: 2.0.0-alpha
            Reporter: Alejandro Abdelnur


HttpFS opens and closes a FileSystem instance against the backend filesystem (typically HDFS) on every request. The FileSystem caching is not used as it does not have expiration/timeout and filesystem instances in there live forever, for long running services like HttpFS this is not a good thing as it would keep connections open to the NN.
