Alex Petrov commented on CASSANDRA-12144: ----------------------------------------- Created broken sstables for both 2.0 and 3.0 storage formats and wrote some unit tests to reproduce the failures and make the review possibly easier. |[3.0|https://github.com/ifesdjeen/cassandra/tree/12144-3.0] |[utest|https://cassci.datastax.com/view/Dev/view/ifesdjeen/job/ifesdjeen-12144-3.0-testall/] |[dtest|https://cassci.datastax.com/view/Dev/view/ifesdjeen/job/ifesdjeen-12144-3.0-dtest/] |[upgrade tests|https://cassci.datastax.com/view/Dev/view/ifesdjeen/job/upgrade_tests-all-12144-3.0/]| |[trunk|https://github.com/ifesdjeen/cassandra/tree/12144-trunk] |[utest|https://cassci.datastax.com/view/Dev/view/ifesdjeen/job/ifesdjeen-12144-trunk-testall/] |[dtest|https://cassci.datastax.com/view/Dev/view/ifesdjeen/job/ifesdjeen-12144-trunk-dtest/] |[upgrade tests|https://cassci.datastax.com/view/Dev/view/ifesdjeen/job/upgrade_tests-all-12144-trunk/]| I'm re-running the tests again (although only changes were my added sstables and tests). Unfortunately, upgrade tests are not very representative as they're throwing similar failures (in similar amounts on [trunk|https://cassci.datastax.com/view/Upgrades/job/upgrade_tests-all/lastCompletedBuild/testReport/]), also failures look more like assertion mismatches. > Undeletable rows after upgrading from 2.2.4 to 3.0.7 > ---------------------------------------------------- > > Key: CASSANDRA-12144 > URL: https://issues.apache.org/jira/browse/CASSANDRA-12144 > Project: Cassandra > Issue Type: Bug > Reporter: Stanislav Vishnevskiy > Assignee: Alex Petrov > > We upgraded our cluster today and now have a some rows that refuse to delete. > Here are some example traces. > https://gist.github.com/vishnevskiy/36aa18c468344ea22d14f9fb9b99171d > Even weirder. > Updating the row and querying it back results in 2 rows even though the id is > the clustering key. > {noformat} > user_id | id | since | type > -------------------+--------------------+--------------------------+------ > 116138050710536192 | 153047019424972800 | null | 0 > 116138050710536192 | 153047019424972800 | 2016-05-30 14:53:08+0000 | 2 > {noformat} > And then deleting it again only removes the new one. > {noformat} > cqlsh:discord_relationships> DELETE FROM relationships WHERE user_id = > 116138050710536192 AND id = 153047019424972800; > cqlsh:discord_relationships> SELECT * FROM relationships WHERE user_id = > 116138050710536192 AND id = 153047019424972800; > user_id | id | since | type > --------------------+--------------------+--------------------------+------ > 116138050710536192 | 153047019424972800 | 2016-05-30 14:53:08+0000 | 2 > {noformat} > We tried repairing, compacting, scrubbing.
