Subject Re: Solr Collection API doesn't seem to be working
Date Thu, 03 Jan 2013 01:50:20 GMT
Unfortunately, for 4.0, the collections API was pretty bare bones. You don't actually get back
responses currently - you just pass off the create command to zk for the Overseer to pick
up and execute.

So you actually have to check the logs of the Overseer to see what the problem may be. I'm
working on making sure we address this for 4.1.

If you look at the admin UI, in the zk tree, you should be able to see what node is the overseer
(look for its election node). The logs for that node should indicate the problem.

FYI, if I remember right, replication factor is not currently optional.

In the future, I'd like it so you can say like replicationFactor=max_int, and the overseer
will periodically try to match that given the nodes it sees - but we don't have that yet.

When you add new nodes, to add them to a current collection you will either have to use CoreAdmin
API or pre configure the cores in solr.xml. All you need is to specify a matching collection
name for the new core.
