Todd Lipcon updated HDFS-1246:
------------------------------
Attachment: hdfs-1246.txt
Attaching patch for branch-0.20-append. It's a bit messy code, not sure if we
actually want to commit as is, but figured others may find it useful to see.
This could be made into a unit test, but I was afraid of orphaning processes,
etc, so it only runs manually against a real cluster right now.
