   > Thanks for the thorough review @abstractdog . I'll address the review 
comments shortly, you can continue the review in the meantime. I hope you are 
able to build the image and start tez am standalone process 😅
   > 
   > I still believe we can get rid of hadoop tarball dependency completely as 
the hadoop dependent required jars are already part of tez tarball. It might 
unnecessary increase docker image size.
   > 
   > Also please suggest should I use 
eclipse-temurin:21.0.3_9-**jre**-ubi9-minimal or **jdk**, in case we want to 
take jstack or other java debugging tools, jkd image is required.
   
   1. I believe as long as a simple DAG can run without adding hadoop jars 
(other than what's already insided tez.tar.gz), it fine to get rid of them: we 
cannot test it now, but we can still check if the AM starts correctly, and if 
so, we're good
   
   2. regarding debugging tools: I would add them in the first round, and we 
can still optimize later: these images are not for production in the first 
round, so I would rather have a slightly bigger image with debugging tools than 
having a small image that's harder to use while investigating something
