Subject [jira] [Commented] (CASSANDRA-13525) ReverseIndexedReader may drop rows during 2.1 to 3.0 upgrade
Date Tue, 16 May 2017 03:22:04 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-13525?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16011677#comment-16011677

Jeff Jirsa commented on CASSANDRA-13525:
----------------------------------------

Code looks good to me.

Looks like I found your circleCI run for [3.0|https://circleci.com/gh/beobal/cassandra/10#tests/containers/2]
:

{code}
Your build ran 4768 tests with 1 failure
testAccessAndSchema-compression - org.apache.cassandra.cql3.ViewSchemaTest
{code}

For [3.11|https://circleci.com/gh/beobal/cassandra/11#tests/containers/2]:

{code}
Your build ran 5959 tests with 2 failures
testNoArgs-compression - org.apache.cassandra.tools.CompactionStressTest
morejava.lang.RuntimeException: java.lang.ClassNotFoundException: org.apache.cassandra.stress.CompactionStress
testWriteAndCompact-compression - org.apache.cassandra.tools.CompactionStressTest
morejava.lang.RuntimeException: java.lang.ClassNotFoundException: org.apache.cassandra.stress.CompactionStress
{code}

Neither of those seem related to this patch, so I'm good with that.

I've kicked off build #49 for 3.0 ( https://builds.apache.org/view/A-D/view/Cassandra/job/Cassandra-devbranch-dtest/
) and #50 for 3.11 , though it'll be quite some time before it's complete (maybe many days).

> During an upgrade from 2.1 (or 2.2) to 3.0 (or 3.x) queries which perform reverse iteration
may silently drop rows from their results. This can happen before sstableupgrade is run and
when the sstables are indexed.
