Nathan Roberts commented on MAPREDUCE-6763: ------------------------------------------- Thanks [~jlowe] for the improvement. This will certainly help busy shuffle handlers although larger clusters will probably want to tune this up well above the default of 128. Patch looks good, +1 (non-binding). > Shuffle server listen queue is too small > ---------------------------------------- > > Key: MAPREDUCE-6763 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-6763 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: mrv2 > Reporter: Jason Lowe > Assignee: Jason Lowe > Attachments: MAPREDUCE-6763.001.patch > > > ShuffleHandler doesn't specify a listen queue length for the server port, so > it ends up getting the default listen queue length of 50. This is too small > to handle bursts of shuffle traffic on large clusters. It's also > inconsistent with the default Hadoop uses for RPC servers (default=128). -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: mapreduce-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: mapreduce-issues-h...@hadoop.apache.org
