dynamic configuration of mapred.map/reduce.tasks
------------------------------------------------
Key: HADOOP-608
URL: http://issues.apache.org/jira/browse/HADOOP-608
Project: Hadoop
Issue Type: Wish
Components: conf
Reporter: Johannes Zillmann
Priority: Minor
Since the optimal value for these 2 configuration properties heavily depends on
the numer of nodes, also examined here
http://wiki.apache.org/lucene-hadoop/HowManyMapsAndReduces
would it be not more comfortable to configure relations to numberOfNodes ?
So you hav'nt to change it all the time the number of nodes changes...
