Job submission RPC more likely to timeout and fail

For the past week, Small Jobs Benchmark has been failing sporadically when run on small, medium and large size clusters. I run it with 30 iterations. It usually fails somewhere between the 12th and 20th iteration with a timeout trying to submit the job. Perhaps the JT is busier now doing counter related work which causes this to timeout. Here's the client side exception:
