Subject [jira] [Commented] (HBASE-17887) Row-level consistency is broken for read
Date Fri, 12 May 2017 10:55:05 GMT

    [ https://issues.apache.org/jira/browse/HBASE-17887?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16007951#comment-16007951

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.
