Subject [jira] [Commented] (CASSANDRA-11353) ERROR [CompactionExecutor] CassandraDaemon.java Exception in thread
Date Thu, 07 Apr 2016 09:38:25 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-11353?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15229999#comment-15229999
] 

Sylvain Lebresne commented on CASSANDRA-11353:
----------------------------------------------

Ok, so something wrong happened to the patch of CASSANDRA-10944 on trunk but it appears I'm
not good enough with git to figure out why. For instance, if I do (on trunk):
{noformat}
git log -p --full-history --follow test/unit/org/apache/cassandra/db/compaction/TTLExpiryTest.java
{noformat}
all I can see is the test for CASSANDRA-10944 being added followed by an inconsequential commit
to the file, but that test isn't there on trunk! So it appears the patch for CASSANDRA-10944
has been reverted somehow but that {{git log}} command doesn't show it. If someone has enough
git fu to find the missing link, I'd be really grateful of the knowledge.

In any case, we just need to re-commit the patch from CASSANDRA-10944, which just needs a
trivial rebase post-CASSANDRA-9472. Running CI to be sure (patch only against trunk since
3.0 correctly has the original patch):
