-------------------------------------

I am still seeing this issue. I am using the 0.19.2 code from around March 19th.

> I'm seeing a lot of "task attempts" around our hadoop cluster for jobs that are no longer
around. The attempts seem to be "hung", as they sit there forever. Additionally, they seem
to take up map and reduce slots in the cluster unless MapReduce is restarted. This causes
real jobs to be unable to utilize the whole cluster.
