Subject [jira] [Updated] (CASSANDRA-5942) bootstrapping new node after upgrading cluster causes counter columns to randomly have incorrect values
Date Thu, 19 Dec 2013 23:22:07 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-5942?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jonathan Ellis updated CASSANDRA-5942:
--------------------------------------

    Fix Version/s:     (was: 2.0.4)

Sounds like the kind of counter bugs that we're addressing in CASSANDRA-6504.  Dunno if you
want to add anything, [~iamaleksey].

>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-5942
>             Project: Cassandra
>          Issue Type: Bug
>         Environment: java version "1.7.0_25"
> Java(TM) SE Runtime Environment (build 1.7.0_25-b15)
> Java HotSpot(TM) 64-Bit Server VM (build 23.25-b01, mixed mode)
>            Reporter: Daniel Meyer
>         Attachments: logs.tar, upgrade_through_versions_test.py

> Running the latest version of upgrade_through_versions_test will randomly fail at a rate
of about 1 out of 5 runs due to an incorrect counter value.  A slightly modified version of
the test is attached for reference.  This version has trunk eliminated from the versions list
and an extra debugging statement.
> The problem occurs after upgrading to the 2.0 branch from the 1.2 branch and after boostrapping
a new node to the cluster.  Best way to repro is just run the test in a loop 5 to 10 times.

> Be sure to set PRINT_DEBUG env variable to true and run test with --nocapture to see
the debug output.  Logs are also included.
