    • Type: Bug
    • Status: Closed
    • Priority: Major
    • Resolution: Fixed
    • Affects Version/s: 0.23.3, 2.0.0-alpha, 3.0.0-alpha1

      Description

      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.
