Hello Mike Likely your existing 3 Zookeeper nodes can serve your expansion requirements You can monitor the CPU and network of the Zookeeper nodes when your Kafka cluster is growing, when reaching the throughput limit, you can expand your zookeeper to 5 nodes Remember the zookeeper nodes need to keep in sync all the time, so the more zookeeper nodes the more traffic will be added to keep them in sync, while those nodes handling the Kafka requests; so it doesn't mean the more the better I would suggest to stay with 3 zookeeper nodes while expanding your kafka cluster with close monitoring, and consider to grow to 5 when the CPU/network throughput reaching the limit You can also consider to tune the zookeeper nodes e.g. dedicated disks, better network throughput, isolate zookeeper process, disable swaps

Hello This may be related to the way you use Hue For example, if you uploading a large file using Import to table option, you may hit the proxy timeout issue, (by default, the timeout is 600 seconds), you can try to increase the proxy timeout option to a larger value, or you can optimise how you get large data files into the cluster by using other tools like NiFi etc
