Jessica Cheng created SOLR-5220:
-----------------------------------
Summary: Marking server as zombie due to 4xx response is odd
Key: SOLR-5220
URL: https://issues.apache.org/jira/browse/SOLR-5220
Project: Solr
Issue Type: Bug
Components: clients - java
Affects Versions: 4.4
Reporter: Jessica Cheng
In LBHttpSolrServer.request, a request is retried and server marked as zombie
if the return code is 404, 403, 503, or 500, and the comment says "we retry on
404 or 403 or 503 - you can see this on solr shutdown". I think returning a 503
on a shutdown is reasonable, but not 4xx, which is supposed to be a client
error. But even if this is can't be fixed systematically on the server-side,
seems like on the client side we can retry on another server, but not mark the
current server as dead, because most likely when the server returns a 403
(Forbidden) or 404 (Not Found), it's not because it's dead.
