----------------------------------------------------
Summary: Data mismatch across the nodes in the cluster
Key: CASSANDRA-16434
URL: https://issues.apache.org/jira/browse/CASSANDRA-16434
Project: Cassandra
Issue Type: Bug
Components: Consistency/Repair
Reporter: Muhammad Junaid Muzammil
Hi,
Recently I have came across one strange issue. On an existing cluster with 12
nodes, there were new nodes launched replacing the older ones. It was ensured
that only one node was being added or removed at a time until it comes to
healthy state. Once the process was completed, we found some data consistency
issues in the cluster. Querying a table from some nodes gave back null results
which wasn't expected. Is this expected behaviour? We are running Cassandra
*3.11.3* version.
Though this problem was solved by running repairs, but it doesn't sound right.
There wasn't any strange thing observed from the Cassandra logs (just a few
timeouts spread over time which is quite normal when a cluster is running).
