Hi Amr, Hadoop contains the FIFO scheduler and two more advanced schedulers, the capacity scheduler, developed at Yahoo, and the fair scheduler, developed at Facebook.
In Hadoop 2, the fair scheduler code is located in the org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair package, and the capacity scheduler code is located in the org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity package. -Sandy On Sun, Apr 21, 2013 at 11:39 AM, Amr Mohammed <amr.elkh...@hotmail.com>wrote: > Please,can any one give me guidelines or help for improving hadoop > performance by improving the scheduling algorithm andwhich classes are > responsible for the scheduling
