With that information, I think I can tell you what went wrong. It looks like one of the files you're trying to upload is 5 megabytes in size. ZooKeeper doesn't allow anything bigger than about 1 megabyte by default, because is not designed for handling large amounts of data. I think that the ZK uploading functionality probably needs to check the size of what it is uploading against the max buffer setting and log a useful error message. You can get this to work, but to do so will require setting a system property on *all* ZK clients and servers. The clients will include Solr itself and the zkcli script. The system property to set is "jute.maxbuffer". Info can be found in ZK documentation. https://zookeeper.apache.org/doc/r3.4.11/zookeeperAdmin.html Thanks, Shawn
