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

             Summary: Update Netty to avoid leaking file descriptors during shuffle
                 Key: HADOOP-8495
                 URL: https://issues.apache.org/jira/browse/HADOOP-8495
             Project: Hadoop Common
          Issue Type: Bug
          Components: io
    Affects Versions: 0.23.3
            Reporter: Jason Lowe
            Assignee: Jason Lowe
            Priority: Critical


Netty 3.2.3.Final has a known bug where writes to a closed channel do not have their futures
invoked.  See [Netty-374|https://issues.jboss.org/browse/NETTY-374].  This can lead to file
descriptor leaks during shuffle as noted in MAPREDUCE-4298.
