---------------------------------------
Summary: bootstrapping new node after upgrading cluster causes
counter columns to randomly have incorrect values
Key: CASSANDRA-5942
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
Fix For: 2.0
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.
