Jason Brown created CASSANDRA-5498: -------------------------------------- Summary: Possible NPE on EACH_QUORUM writes Key: CASSANDRA-5498 URL: https://issues.apache.org/jira/browse/CASSANDRA-5498 Project: Cassandra Issue Type: Bug Components: Core Affects Versions: 1.1.10 Reporter: Jason Brown Priority: Minor Fix For: 1.1.12, 1.2.5, 2.0
When upgrading from 1.0 to 1.1, we observed that DatacenterSyncWriteResponseHandler.assureSufficientLiveNodes() can throw an NPE if one of the writeEndpoints has a DC that is not listed in the keyspace while one of the nodes is down. We observed this while running in EC2, and using the Ec2Snitch. The exception typically was was brief, but a certain segment of writes (using EACH_QUORUM) failed during that time. This ticket will address the NPE in DSWRH, while a followup ticket will be created once we get to the bottom of the incorrect DC being reported from Ec2Snitch. -- This message is automatically generated by JIRA.
