Vinod K V resolved HADOOP-6749. ------------------------------- Resolution: Duplicate Hong is right, I am closing this as duplicate of MAPREDUCE-1379. Please read the discussions there and reopen this one if you don't agree. > Add mapred.tasktracker.tasks.maximum to limit the total number of map and > reduce tasks > -------------------------------------------------------------------------------------- > > Key: HADOOP-6749 > URL: https://issues.apache.org/jira/browse/HADOOP-6749 > Project: Hadoop Common > Issue Type: New Feature > Components: conf > Affects Versions: 0.20.2 > Reporter: Ted Yu > > We have mapred.tasktracker.map.tasks.maximum and > mapred.tasktracker.reduce.tasks.maximum now. > It is desirable to have mapred.tasktracker.tasks.maximum which limits the > total number of map and reduce tasks. Meaning its value may be lower than > (mapred.tasktracker.map.tasks.maximum + > mapred.tasktracker.reduce.tasks.maximum) > This would be useful in a cluster whose nodes are multi-core. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
