Hi @Khaja_Zaffer ,

Maybe there is some capacity problem in AWS now?

Another thing, there is a following  limitation in databricks community edition -> you need to create a new cluster every-time and run it. Even in the same session if your cluster stops due to inactivity or some other reason, you will need to create a new cluster.

So, do you want to reuse already created cluster? If so, it's not possible. You need to create new one.
