[jira] [Created] (HDFS-3359) DFSClient.close should close cached sockets

Todd Lipcon created HDFS-3359:
---------------------------------

             Summary: DFSClient.close should close cached sockets
                 Key: HDFS-3359
                 URL: https://issues.apache.org/jira/browse/HDFS-3359
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: hdfs client
    Affects Versions: 0.22.0, 2.0.0
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon
            Priority: Critical


Some applications like the TT/JT (pre-2.0) and probably the RM/NM cycle through DistributedFileSystem objects reasonably frequently. So long as they call close() it isn't a big problem, except that currently DFSClient.close() doesn't explicitly close the SocketCache. So unless a full GC runs (causing the references to get finalized), many SocketCaches can get orphaned, each with many open sockets inside. We should fix the close() function to close all cached sockets.
