Re: Multicore clustering setup problem

I'd probably need to take a look at the whole Solr dir you're working with,
clearly there's something wrong with the classpath of core1.

I'm not an expert on Solr's internals related to core management, but I once
did configure two cores with search results clustering, where clustering
configuration and <lib>s were specified for each core separately, so this is
unlikely to be a problem. Another approach would be to put all the JARs
required for clustering in a common directory and point Solr to that lib
using the sharedLib attribute in the <solr> tag:
http://wiki.apache.org/solr/CoreAdmin#solr. But it really should work both
ways.

If you can somehow e-mail (off-list) the listing of your Solr directory and
contents of your configuration XMLs, I may be able to trace the problem for
you.
