jobs don't get executed in parallel

Key: HADOOP-295
URL: http://issues.apache.org/jira/browse/HADOOP-295
Project: Hadoop
Type: Bug
Components: mapred
Reporter: Yoram Arnon
Assigned to: Mahadev konar
we expect tasks to be assigned to nodes up to their configured capacity, with
separate slots for map and reduce tasks.
we're observing jobs queueing up, with the map slots free, as exemplified by
this copy-paste (converted to text) of the JT WI page.
