Hi Zahid
You have completely missed my question. As you would be aware, there are four ways to setup Ubuntu…a) Ubuntu as base operating system. B) Ubuntu On Docker c) Ubuntu on Windows HyperV and d) Ubuntu on Windows WSL (Windows Subsystem for Linux). There are no issues with Zeppelin and Flink running with options a,b and c. However, there is an issue with Ubuntu run as Windows WSL. I request readers of this blog to answer this specific question if they have good understanding of Windows WSL. The issue is not with Ubuntu, Flink or Zeppelin. It is to do with WSL.

Ubuntu Version 19 and 20. Your error is quite specific! Looking at the error messages it seems to me there is port conflict . Java code describes what it is doing. Perhaps try the setup using the instructions I mentioned previously to eliminate one cause of error. May be they will work for you. Especially if you have flink and Zeppelin installed on same machine.

The issue is running Zeppelin with flink interpreter on WSL ubuntu linux. Have you tried running Zeppelin 0.9 on Windows WSL linux and tried connecting to Flink instance?

Since WSL does not allow creation of random ports, flink interpreter fails as below. Any suggestion is much appreciated.
