Subject Re: Solr4.7 No live SolrServers available to handle this request
Date Mon, 24 Mar 2014 14:25:50 GMT
Sathya,

We're still missing a fair amount of information here though it looks like your cluster is
healthy. How are you indexing and what's the request you're sending that results in the error
you're seeing? Have you checked your nodes' logs for errors that correspond with the one you're
seeing while indexing?

Thanks,
Greg
