> improve performance of map output transfers > ------------------------------------------- > > Key: HADOOP-195 > URL: http://issues.apache.org/jira/browse/HADOOP-195 > Project: Hadoop > Type: Improvement > Components: mapred > Versions: 0.2 > Reporter: Owen O'Malley > Assignee: Owen O'Malley > Fix For: 0.3.0 > Attachments: MapFileSimulator.java, data-transfer-chart.pdf, > mapfilesimulator-big.txt, mapfilesimulator-sort2.txt, netstat.log, > netstat.xls, parallel-copiers.txt > > The data transfer of the map output should be transfered via http instead > rpc, because rpc is very slow for this application and the timeout behavior > is suboptimal. (server sends data and client ignores it because it took more > than 10 seconds to be received.) -- 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
