[jira] [Commented] (CASSANDRA-11418) Nodetool status should reflect
hibernate/replacing states
[ https://issues.apache.org/jira/browse/CASSANDRA-11418?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17392008#comment-17392008 ]
Thomas Steinmaurer commented on CASSANDRA-11418:
------------------------------------------------
As 4.0 has been released, is this something which could be picked up in the near future, perhaps even for the 3.11 series?
Reason is that showing a node in normal state when using replace_address is not only confusing for operators, but especially for any automation/monitoring tooling behind a Cassandra cluster.
Additionally, when a Cassandra process disables Gossip (and client protocols) due to disk issues, other nodes will see it as DN but running nodetool on this particular node will report UN, although Gossip is disabled. This is additionally confusing for any automation/monitoring tooling.

> Currently, the four options for state in nodetool status are joining/leaving/moving/normal.
> Joining nodes are determined based on bootstrap tokens, leaving nodes are based on leaving endpoints in TokenMetadata, moving nodes are based on moving endpoints in TokenMetadata.
> This means that a node will appear in normal state when going through a bootstrap with flag replace_address, which can be confusing to operators.
> We should add another state for hibernation/replacing to make this visible. This will require a way to get a list of all hibernating endpoints.
