Subject run yarn container as specific user
Date Thu, 11 Dec 2014 20:04:50 GMT
I'm able to use the UGI.doAs(..) to launch a yarn app and, through the
ResourceManager, both the ApplicationMaster and Containers are
associated with the correct user.  But the process on the node itself
really runs as the yarn user.  The problem is that the yarn app writes
data to DFS and its being written as yarn, since that's what the real
process is.  This is an non-secure cluster.  I've yet to stumble upon
a solution that doesn't feel icky.  What's the right way to achieve
this?

Thanks,
