Subject [jira] Created: (HADOOP-295) jobs don't get executed in parallel
Date Tue, 13 Jun 2006 00:27:29 GMT
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.
