---------------------------------------
Labels: qa-resolved (was: )
> Data loss after moving tokens
> -----------------------------
>
> Key: CASSANDRA-7836
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7836
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Environment: OSX and Ubuntu 14.04
> Reporter: Philip Thompson
> Assignee: Tyler Hobbs
> Priority: Critical
> Labels: qa-resolved
> Fix For: 2.1.0
>
> Attachments: 7863-2.1.0.txt, topology_test.py
>
>
> The dtest topology_test:TestTopology.movement_test is failing on 2.1.0 and
> 2.1-HEAD. The test, which has been attached, goes through the following
> workflow:
> - Create an unbalanced three node cluster without vnodes
> - Create a keyspace with RF=1
> - Load data into the cluster
> - Flush the cluster with nodetool flush
> - Move the tokens around to balance the cluster, using nodetool move
> - Run nodetool cleanup
> At this point, the test checks that all 10,000 of the originally inserted
> rows are still there. In 2.0.10 that is true, however in 2.1, only ~4000 rows
> exist.
