bq. TestZKLessAMOnCluster consistently fails
Taking a look. I remember last time I ran, this one was flaky but didn't see consistent errors.

I re-ran just TestZKLessAMOnCluster 5 times each on a local Mac dev box and an EC2 Amazon
Linux instance. On the Mac it passed each time. On the Linux instance it failed quite often,
once every 2 or 3 times, with the same error seen previously:
