------------------------------------------
Summary: Data loss after nodetool taketoken
Key: CASSANDRA-7601
URL: https://issues.apache.org/jira/browse/CASSANDRA-7601
Project: Cassandra
Issue Type: Bug
Components: Core, Tests
Environment: Mac OSX Mavericks. Ubuntu 14.04
Reporter: Philip Thompson
Priority: Minor
Attachments: consistent_bootstrap_test.py, taketoken.tar.gz
The dtest
consistent_bootstrap_test.py:TestBootstrapConsistency.consistent_reads_after_relocate_test
is failing on HEAD of the git branches 2.1 and 2.1.0. It is passing on 1.2 and
2.0.
The test performs the following actions:
- Create a cluster of 3 nodes
- Create a keyspace with RF 2
- Take node 3 down
- Write 980 rows to node 2 with CL ONE
- Flush node 2
- Bring node 3 back up
- Run nodetool taketoken on node 3 to transfer 80% of node 1's tokens to node 3
- Check for data loss
When the check for data loss is performed, only ~725 rows can be read via CL
ALL.
