Hello, Thanks for the response. I had already tried setting the log level to debug in log4j-cli.properties, logback-console.xml, and log4j-console.properties but no additional relevant information comes out. On the server, all that comes out are zookeeper ping responses: 2018-09-05 15:16:56,786 DEBUG org.apache.flink.shaded.zookeeper.org.apache.zookeeper.ClientCnxn - Got ping response for sessionid: 0x3659b60bcb50076 after 1ms

For the client, look for log messages starting with "Sending request of", this will contain the host and port that requests are sent to by the client. Verify that these are correct and match the host/port that you use when accessing the web UI. For the server, look for log messages starting with "Received request", so we can figure out whether the request at least arrives.

I have looked at the zookeeper data and it is all present. I have tried running the command on multiple nodes and they all give the same error. I looked for a verbose or debug option for the commands but found nothing. Suggestions on this? Thanks, Jason
