[jira] Created: (MAPREDUCE-1279) "mapred queue -list" will
unnecessarily download JobStatus information also
"mapred queue -list" will unnecessarily download JobStatus information also
---------------------------------------------------------------------------
Key: MAPREDUCE-1279
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1279
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: client, jobtracker
Reporter: Vinod K V
"mapred queue -list" does a Cluster.getRootQueues() and thus will download the entire queue-hierarchy _including_ all the (potentially large number of) jobs' information. This is not needed and avoiding it can significantly lower the data transferred from JT.
