[jira] [Updated] (MAPREDUCE-4298) NodeManager crashed after running out of file descriptors

     [ https://issues.apache.org/jira/browse/MAPREDUCE-4298?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jason Lowe updated MAPREDUCE-4298:
----------------------------------

    Attachment: MAPREDUCE-4298.patch

Patch to update Netty version from 3.2.3.Final to 3.2.4.Final.  I manually tested it on a single-node cluster to verify a broken pipe during the write of the shuffle header doesn't lead to a leaked file descriptor.
