Keith Wansbrough created CASSANDRA-12424:
--------------------------------------------
Summary: Assertion failure in ViewUpdateGenerator
Key: CASSANDRA-12424
URL: https://issues.apache.org/jira/browse/CASSANDRA-12424
Project: Cassandra
Issue Type: Bug
Reporter: Keith Wansbrough
Using released apache-cassandra-3.7.0, we have managed to get a node into a
state where it won't start up. The exception is {{java.lang.AssertionError: We
shouldn't have got there is the base row had no associated entry}} and it
appears in
ViewUpdateGenerator.computeLivenessInfoForEntry(ViewUpdateGenerator.java:455).
I still have the offending node; what diags/data would be useful for diagnosis?
I've attached the full cassandra.log. In summary, cassandra.log contains
multiple instances of the following when replacing the commit log on startup,
leading ultimately to failure to start up.
