You're in uncharted territory. I can imagine you use
a SolrCloud cluster as a separate Solr for a federated
search, but using it as a single shard just seems wrong.
If nothing else, indexing to the shards will require that
the documents be routed correctly. But having one
shard in SolrCloud and another shard managed
externally seems ripe for getting the docs indexed
to various shards you're not expecting, unless you're
using explicit routing....
All in all, this _really_ sounds like something you should
not be attempting. Why are you trying to do this? Is it
possible to just set up a SolrCloud cluster and index
all the docs to it and be done with it?
'cause I think you'll end up with endless problems given
what you've described.
