Hi Shawn, You can get the current jute.maxbuffer setting from a running ZooKeeper instance by querying ZooKeeperServerBean via JMX.
Currently there're 2 usage of the setting in ZK: 1) server-client communication which is by default 4MB, 2) server-server communication which is by default 1MB. They can't be set individually, but can be overriden with the jute.maxbuffer system property. Do I understand correctly that Solr uploads file to ZooKeeper?
