> Flakiness in TestAsyncKuduSession
> ---------------------------------
>
> Key: KUDU-1521
> URL: https://issues.apache.org/jira/browse/KUDU-1521
> Project: Kudu
> Issue Type: Bug
> Components: client
> Affects Versions: 0.9.1
> Reporter: Adar Dembo
> Assignee: Todd Lipcon
> Priority: Major
> Attachments:
> org.apache.kudu.client.TestAsyncKuduSession-TableIsDeleted-output.txt,

>
> 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:
