Erick Erickson created SOLR-11427:
-------------------------------------
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.
