[jira] Updated: (HADOOP-6978) Add JNI support for secure IO operations

     [ https://issues.apache.org/jira/browse/HADOOP-6978?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Todd Lipcon updated HADOOP-6978:
--------------------------------

    Attachment: hadoop-6978.txt

Here's a patch against trunk. It's large due to regenerating autotools - I agree with a previous comment (I think by Arun) that we should stop checking this stuff in some day, but that's out of scope for this patch.

> In support of MAPREDUCE-2096, we need to add some JNI functionality. In particular, we need the ability to use fstat() on an open file stream, and to use open() with O_EXCL, O_NOFOLLOW, and without O_CREAT.
