Description

I am seeing two fails:

java.lang.AssertionError: expected:<0> but was:<-1>
	at __randomizedtesting.SeedInfo.seed([7AEAA2B65C8B6219:F2BE9D6CF2770FE1]:0)

and

The first issue requires digging into the job logs to see what is actually going wrong.

The second may mean we need to raise the connect timeout YARN is using if possible.
