----------------------------------------
Summary: Unable to ALTER KEYSPACE while
decommissioned/assassinated nodes are in gossip
Key: CASSANDRA-16422
URL: https://issues.apache.org/jira/browse/CASSANDRA-16422
Project: Cassandra
Issue Type: Improvement
Components: Consistency/Bootstrap and Decommission
Reporter: Jon Meredith
Assignee: Jon Meredith
As part of Transient Replication added in CASSANDRA-14404, {{ALTER KEYSPACE}}
had a validation check added to verify no range movement was taking place.
The check requires all nodes to be in {{NORMAL}} state. When a node is
decommissioned or assassinated then it will remain in gossip for 3 days in
{{LEFT}} state (by default), preventing any keyspace alteration until it has
expired from gossip, even though it is safe to make the change.
The validation condition should be changed to all nodes being in {{NORMAL}} or
{{LEFT}} state instead.
