Capacity Scheduler data local tasks are about 40%-50% which is not good.
While my test with 70 node cluster i consistently get data locality around 40-50% on a free cluster.
I think we need to implement something like delay scheduling in the capacity scheduler for improving the data locality.
After implementing the delay scheduling on Hadoop 22 I am getting 100 % data locality in free cluster and around 90% data locality in busy cluster.
