What is the pros and cons of having Zookeeper instance and Solr instance in the same VM/Server in production environment?
If you have sufficient CPU, memory, and I/O resources on the system for both roles, there is no problem with putting both on the same server. If possible, the ZK database should be on a separate physical disk than Solr uses for indexes, but if index is not handling a high loa, even that may not be necessary.
The major recommendation is that the ZK server should not be embedded in Solr. It should be a separate process, so that it doesn't go down when Solr is stopped.
Putting ZK and Solr on completely separate physical servers does give the best results, but for many setups, isn't strictly required.
