The length that it is complaining about is a very large number -- 1.3 billion. The error message excludes the detail I would need to learn whether it comes from Zookeeper or Solr. If it's coming from zookeeper, your zookeeper database contains a node whose size is over a thousand times larger than what zookeeper supports by default. The default maximum for znode size is about one megabyte. If you're running a recent version of Solr (5.x or later), the most likely culprit for a large znode is the overseer queue ... but to reach a overseer queue size of 1.3 billion bytes would probably require an extremely large cluster with thousands of cores, and that cluster would likely be experiencing a lot of stability issues. This is a situation that even a full Solr install has trouble handling -- I would never try to do it with a test class like MiniSolrCloudCluster. I could also be completely wrong, but without detailed logs and more information on what you're trying to build, it's impossible for me to say. Thanks, Shawn
