Subject [jira] [Commented] (CASSANDRA-9752) incremental repair dtest flaps on 2.2
Date Wed, 20 Jan 2016 19:34:39 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-9752?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15109245#comment-15109245

Jim Witschey commented on CASSANDRA-9752:
-----------------------------------------

[~philipthompson] Sounds right, we've got 30G memory to play with. Do we know how many nodes
the dtests top out at? I doubt it's above 10.

> {{incremental_repair_test.py:TestIncRepair.multiple_subsequent_repair_test}} flaps on
2.2. It's hard to tell what failures are repair-specific, but there are a few distinct failures
I've seen recently:
> - [an NPE in StorageService|http://cassci.datastax.com/view/cassandra-2.2/job/cassandra-2.2_dtest/143/testReport/junit/incremental_repair_test/TestIncRepair/multiple_subsequent_repair_test/]
> - [an NPE in SSTableRewriter|http://cassci.datastax.com/view/cassandra-2.2/job/cassandra-2.2_dtest/135/testReport/junit/incremental_repair_test/TestIncRepair/multiple_subsequent_repair_test/].
I believe this is related to CASSANDRA-9730, but someone should confirm this.
> - [an on-disk data size that is too large|http://cassci.datastax.com/view/cassandra-2.2/job/cassandra-2.2_dtest/133/testReport/junit/incremental_repair_test/TestIncRepair/multiple_subsequent_repair_test/]
> You can find the test itself [here on GitHub|https://github.com/riptano/cassandra-dtest/blob/master/incremental_repair_test.py#L206]
and run it with the command
> {code}
> CASSANDRA_VERSION=git:trunk nosetests incremental_repair_test.py:TestIncRepair.multiple_subsequent_repair_test
> {code}
> Assigning [~yukim], since you're the repair person, but feel free to reassign to whoever's
appropriate.
