Subject Re: Capacity Scheduler APIs
Date Thu, 15 Mar 2012 18:38:26 GMT
Hi Harshad,

Have you looked into CapacitySchedulerConf.java class?
http://www.java2s.com/Open-Source/Java/Database-DBMS/hadoop-0.20.1/org/apache/hadoop/mapred/CapacitySchedulerConf.java.htm

I don't know whether it can be done without restarting the cluster or
namenode.
