Subject [jira] [Commented] (HBASE-16771) VerifyReplication should increase GOODROWS counter if re-comparison passes
Date Sat, 08 Oct 2016 19:41:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16771?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15558589#comment-15558589
] 

Ted Yu commented on HBASE-16771:
--------------------------------

{code}
          Result.compareResults(sourceResult, replicatedResult);
{code}
When the above line doesn't throw exception, the re-comparison passes.
But the row may actually be deleted, leading to empty Result.
GOODROWS counter is not incremented for the above case.

> HBASE-16423 added re-comparison feature to reduce false positive rate.
> However, before logFailRowAndIncreaseCounter() is called, GOODROWS counter is not incremented.
Neither is GOODROWS incremented when re-comparison passes.
> This may produce inconsistent results across multiple runs of the same verifyrep command.
