Description David Gloe 2014-12-04 05:48:14 MST 
Rather than state draining, sinfo shows mixed in 14.11. Is this intended?

The node without a job on it correctly shows drained but the one with a job on it is mixed. Even if the job is exclusive, the node is shown as mixed when it is changed to drain.

No, it should be displayed as draining. Commit 0390788c93d.
