Shawn Heisey commented on SOLR-4194:
------------------------------------
Now I'm really confused. I didn't update to a new revision, but I did change
swappable to true in solr.xml and restart. Now I am getting a bunch of
exceptions. I am still getting most of what you see in the previous solr.log
provided, but the last two lines have been replaced with this:

> PingRequestHandler - shards parameter inherited from search handler definition
> ------------------------------------------------------------------------------
>
> Key: SOLR-4194
> URL: https://issues.apache.org/jira/browse/SOLR-4194
> Project: Solr
> Issue Type: Bug
> Affects Versions: 4.1
> Environment: solr-impl 4.1-SNAPSHOT 1421496 - ncindex - 2012-12-13
> 14:56:25
> Reporter: Shawn Heisey
> Fix For: 4.1, 5.0
>
>
> Included in all my cores is a PingRequestHandler named /admin/ping, which I
> use to enable/disable the server from the perspective of a load balancer
> running haproxy. The handler includes a qt parameter set to /lbcheck.
> I have a special core defined (I call it a broker) that includes the shards
> parameter in most of its search handler definitions. This includes /select,
> /lbcheck, and others.
> When the /admin/ping handler is called, the query is sent to the /lbcheck
> parameter as expected, which gets distributed because it includes shards. If
> one of those shards happens to be down, the handler will give an error
> response to the load balancer.
> The problem is that the PingRequestHandler seems to inherit the shards
> parameter from the search handler it is using, which causes the /admin/ping
> request itself to be distributed, which is not what I want. The individual
> shards are not used by the load balancer, so they always remain disabled.
> This works perfectly in 3.5.0. The official 4.0.0 release has not been
> tested.
> Config and log data will follow in the comments.
