[jira] [Created] (CASSANDRA-14577) gc_grace_seconds should include
UJ (Up/Joining) status period
John Knost created CASSANDRA-14577:
--------------------------------------
Summary: gc_grace_seconds should include UJ (Up/Joining) status period
Key: CASSANDRA-14577
URL: https://issues.apache.org/jira/browse/CASSANDRA-14577
Project: Cassandra
Issue Type: Improvement
Components: Coordination
Environment: Issue observed in environment running Contrail 3.0.3.3-22/Cassandra 2.1.13
Reporter: John Knost
Partial network connectivity (e.g. and MTU mismatch that blackholes jumbo frames) can cause a node to get stuck in a permanent UJ status (as reflected in nodetool). It's possible the node can stay in this way for an extended period of time. Once the isolated node rejoins due to a network repair, it can cause extensive data loss to the healthy nodes.
If the node were completely isolated gc_grace_seconds would prevent the node from joining after the specified period. Other corner cases besides "DN" should be covered if applicable.
