[[ Old comment, sent by email on Wed, 31 May 2006 10:02:17 -0700 ]] This may actually turn out to be high-ish prioority > map-reduce job overhead is too high > ----------------------------------- > > Key: HADOOP-55 > URL: http://issues.apache.org/jira/browse/HADOOP-55 > Project: Hadoop > Issue Type: Bug > Components: mapred > Affects Versions: 0.2.0 > Reporter: Yoram Arnon > Assigned To: Sameer Paranjpye > Priority: Minor > > map-reduce job overhead is too high. Running a null map-reduce job, with no > input, no intermediate data and no output, on a several-hundred node cluster, > takes several minutes, rather than several seconds. > Enhanced distribution, launching and monitoring mechanisms should reduce the > overhead to levels that match human online patience for short jobs. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
