Ravi Gummadi updated MAPREDUCE-18: ---------------------------------- Attachment: MR-18.v1.patch Attaching patch with the suggested changes. > Under load the shuffle sometimes gets incorrect data > ---------------------------------------------------- > > Key: MAPREDUCE-18 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-18 > Project: Hadoop Map/Reduce > Issue Type: Bug > Reporter: Owen O'Malley > Assignee: Ravi Gummadi > Priority: Blocker > Attachments: MR-18.patch, MR-18.v1.patch > > > While testing HADOOP-5223 under load, we found reduces receiving completely > incorrect data. It was often random, but sometimes was the output of the > wrong map for the wrong map. It appears to either be a Jetty or JVM bug, but > it is clearly happening on the server side. In the HADOOP-5223 code, I added > information about the map and reduce that were included and we should add > similar protection to 0.20 and trunk. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
