             Summary: DELETEREPLICA with onlyIfDown specified should succeed if the host node is not present in the live_nodes Znode
                 Key: SOLR-11427
                 URL: https://issues.apache.org/jira/browse/SOLR-11427
             Project: Solr
          Issue Type: Bug
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: Erick Erickson
            Assignee: Erick Erickson


The title says it pretty much, so opening up for discussion:

Here's the problem. Let's say a node is killed via {{kill -9}}. The state.json file still says it's "active", but the node is gone from live_nodes. If the node in question never comes back, the replica's state doesn't necessarily get switched to "down", so specifying onlyIfDown fails with "node is active" message. This is all documented more thoroughly in SOLR-9361.

The question is whether it's sufficient and/or safe to succeed in deleting the replica from state.json if the state is "active" _and_ the node is NOT present in live_nodes.

I'm assigning to myself, but others should feel free to take it.
