Subject [jira] [Commented] (HADOOP-6311) Add support for unix domain sockets to JNI libs
Date Fri, 12 Oct 2012 01:01:16 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6311?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13474694#comment-13474694
] 

Andy Isaacson commented on HADOOP-6311:
---------------------------------------

Thinking about this further, it seems like the native code should be the minimal possible,
and the database of which FDs are accessible should be managed in Java code.  This would remove
the need for the red-black tree in C, and it would make the whole patch much smaller.  Todd
suggested a way to completely avoid needing the cookie, as well.
