Anoop Sam John commented on HBASE-17887:
----------------------------------------
I dont mean keep scanners over old active, pipeline and snapshot. I mean over
the active and pipeline alone.. Snapshot is any way gone now and we have the
new file and we create a scanner over it and done the seek. The scanners over
active and pipeline are in proper pos already. Creating new scanners will do
new seeks. Any way it is ok we fix this way now and see later any better way.
Ya this is a serious problem Yu Li.

> 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.
