It is possible
What kind of node are you using, what other  processes are running? what are the Xmx for NN
and JT ?

Hi,
I am experiencing slow startup times when submitting a MapReduce job (single node cluster
for testing purposes) and was hoping someone could confirm that this was expected behavior.
 Even a job that does absolutely no processing takes 20-30 seconds to complete.  Is this expected?
 If not, what is the rough minimum time to kick off a newly submitted job?

Thanks,-Scott
