Major Description
I've been trying to parse the various failures in http://104.196.14.100/job/kudu-gerrit/2270/BUILD_TYPE=RELEASE. Here's what I see in the test:
The way test() tests AUTO_FLUSH_BACKGROUND is inherently flaky; a delay while running test code will give the background flush task a chance to fire when the test code doesn't expect it. I've seen this cause lead to no PleaseThrottleException, but I suspect the first block of test code dealing with background flushes is flaky too (since it's testing elapsed time).
There's also some test failures that I can't figure out. I've pasted them below for posterity:
