Building Cube in Apache Kylin hangs on the second step

Question

I am trying to buld a Cube in Kylin.

It successfully does the first step and then just keeps running always at 50%

Log from the step 2:

After some time no new logs come in anymore.

What can I do do debug or find an error?

I am using Kylin from Docker container: https://kylin.apache.org/docs/install/kylin_docker.html
