Subject [jira] [Commented] (CASSANDRA-12651) Failure in SecondaryIndexTest.testAllowFilteringOnPartitionKeyWithSecondaryIndex
Date Fri, 25 Nov 2016 12:55:58 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-12651?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15695805#comment-15695805
] 

Alex Petrov commented on CASSANDRA-12651:
-----------------------------------------

Brilliant research, [~beobal]! Sorry I couldn't repro / fix it myself. I guess I just got
overly convinced in the fact it was something wrong with tests. The {{DecoratedKey}} jump
from 5 to 0 certainly proves the point. I've also read the [CASSANDRA-12590] discussion, so
it does look like these both are consequences of the same problem. As far as I understood,
the second (empty) constructor was added in order to avoid assertion failure when {{null}}
is passed (tried it locally without). 

I have to mention that segfault results are shadowed by cassci, for example [here|https://cassci.datastax.com/view/Dev/view/ifesdjeen/job/ifesdjeen-12651-segfault-testall/1/].
We see that the VM exited abnormally, although all the other tests are just skipped, so this
is why we may have never seen segfaults mentioned in [CASSANDRA-12590] (might be for other
reasons). I'll open up the issue.

+1 from my side.
