Hello, I'm having quite a bit of trouble indexing content in Solr Cloud. I build a content indexer on top of the REST API designed to index my data quickly. It was working very well indexing about 100 documents per "<add>" instruction.
After some tweaking of the schema I switched on a few more servers. Set up a few shards and started indexing data. Everything was working perfectly, but as soon as I switched to "Cloud" I started getting RemoteServerExceptions "Illegal to have multiple roots." I'm using the stock Jetty container on both servers. To get things working I reduced the number of documents per add until it worked. Unfortunately that has limited me to adding a single document per add - which is quite slow. I'm fairly sure it's not the size of the HTTP post because things were working just fine until I moved over to Solr Cloud. Does anyone have any information about this problem? It sounds a lot like Sai Gadde's https://issues.apache.org/jira/browse/SOLR-5402 Thanks so much! -Dave
