Anoop Sam John commented on HBASE-17887:
----------------------------------------
Trying to understand the issue and discussion points here.
So here seems the issue is that the test case is making quick flushes. 1st
flush done and before the resetScannerStack, another flush happened and scanner
is not created over the new (?)
But the scan was started at the 1st memstore time and its read point will be <
max of the seqId in the memstore. Whatever be the write to new memstore
happened and so new flushes (2nd) all seqId will be greater than this scan's
readPnt no? So what is the issue then? Sorry if am missing some thing

> As per the flaky tests dashboard here:
> https://builds.apache.org/job/HBASE-Find-Flaky-Tests/lastSuccessfulBuild/artifact/dashboard.html,
> It fails 30% of the time.
> While working on HBASE-17863, a few verification builds on patch failed due
> to TestAcidGuarantees didn't pass. IMHO, the changes for HBASE-17863 are
> unlikely to affect get/ put path.
> I ran the test with and without the patch several times locally and found
> that TestAcidGuarantees fails without the patch similar number of times.
> Opening blocker, considering acid guarantees are critical to HBase.
