------------------------------------------
Summary: WriteTimeoutException thrown when LWT concurrency > 1,
despite the query duration taking MUCH less than cas_contention_timeout_in_ms
Key: CASSANDRA-9328
URL: https://issues.apache.org/jira/browse/CASSANDRA-9328
Project: Cassandra
Issue Type: Bug
Components: Core
Reporter: Aaron Whiteside
Priority: Critical
Attachments: CassandraLWTTest.java
WriteTimeoutException thrown when LWT concurrency > 1, despite the query
duration taking MUCH less than cas_contention_timeout_in_ms.
Unit test attached, run against a 3 node cluster running 2.1.5.
If you reduce the threadCount to 1, you never see a WriteTimeoutException. If
the WTE is due to not being able to communicate with other nodes, why does the
concurrency >1 cause inter-node communication to fail?
