---------------------------------

             Summary: FileContext HDFS implementation can leak socket caches
                 Key: HDFS-3373
                 URL: https://issues.apache.org/jira/browse/HDFS-3373
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: hdfs client
    Affects Versions: 2.0.0
            Reporter: Todd Lipcon


As noted by Nicholas in HDFS-3359, FileContext doesn't have a close() method, 
and thus never calls DFSClient.close(). This means that, until finalizers run, 
DFSClient will hold on to its SocketCache object and potentially have a lot of 
outstanding sockets/fds held on to.
