   @suneet-s the total 900mb of the docker image are manly produced by two docker commands and their produced layers. The second layer is produced by exact the same data, but with different rights (by chown -R druid:druid /opt).
   @gianm Thanks for pointing that.
   Smaller images are good for faster startup in environments that need to download/upload the image.

   I don't have an automated test and i don't know your testing for your Dockerfile either, but i use this changes for an own docker image (based on the changes i did) in our environment (tested and in production).
