[jira] [Updated] (MAPREDUCE-3782) teragen terasort jobs fail when using webhdfs://

     [ https://issues.apache.org/jira/browse/MAPREDUCE-3782?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jason Lowe updated MAPREDUCE-3782:
----------------------------------

    Attachment: MAPREDUCE-3782.patch

Patch for TeraOutputFormat delegation token fix.  No automated testcase, but I did manually test on a secure cluster and verified that teragen obtains the delegation token for webhdfs.
