--------------------------------------------------------------
Yes, I am using the default shuffle manager in spark 1.5 which is sort based.
Also, the default ulimit -n is 1024 for which --total-executor-cores=60 (12
cores/executor) is successful. So, if am increasing it to 10k it should pass
for 120 cores (24 cores/executor).
