Subject Re: Hadoop Scheduling Algorithm
Date Sun, 21 Apr 2013 20:54:08 GMT
Hi,

Addition to Sandy, there is one more scheduler called HOD (Hadoop on
Demand). Please go through the following links to get more details on
schedulers.

HOD - http://hadoop.apache.org/docs/r1.1.2/hod_scheduler.html
Fair - http://hadoop.apache.org/docs/r1.1.2/fair_scheduler.html
Capacity - http://hadoop.apache.org/docs/r1.1.2/capacity_scheduler.html

Thanks
Naga
