This test has gotten flaky with a concerning failure mode (seeing "wrong" results, not just a timeout or something):
http://dist-test.cloudera.org:8080/test_drilldown?test_name=tablet_history_gc-itest It seems like it got flaky starting with Alexey's commit bc14b2f9d775c9f27f2e2be36d4b03080977e8fa which switched it to use AUTO_FLUSH_BACKGROUND. So perhaps the bug is actually a client bug and not anything to do with GC. Alexey, do you have time to take a look, and perhaps consult with Mike if you think it's actually a server-side bug? -Todd -- Todd Lipcon Software Engineer, Cloudera
