Based on /mnt/c/ you are using Windows?

[HariPandey8]

Yes correct I using windows wsl feature on which I m trying to setup but after trying multiple time I got success for once where all services were up and running but when I tried to restart it again then zookeeper service is up but enable start Kafka and giving error failing to start kafka

[OneCricketeer]

I would suggest not using WSL, and rather use the windows/*.bat files for each respective service.

Plus, running the beta builds might not be as stable as the official releases

[HariPandey8]

Thank you.

I tried with official build as well I took the clone of master repo. Same there as well. Why I am trying to setup this on wsl as I want to use KSQL which I didn't find for window.

[OneCricketeer]

I was referring to Kafka and Zookeeper windows scripts, actually.

Regarding the problem, it seems to be related to #402. The alternatives being Cygwin, Docker, or just a VM
