   > That also sounds like a better option (in my opinion), but then we would 
have to define a default path because setting an environment variable for the 
system will be hard.
   
   I think this is just a decision we have to make at some point. there are 
many good options for install location `/etc/systemds/...` or `/lib/systemds` ? 
If we do make such a decision we could provide a install for Ubuntu, `sudo apt 
install systemds`!
   
   > Also we would not like to download all the jars, which would save us no 
download work, but instead anyway set the jars to download, so why not do it 
when building the package and distribute it combined? That would also lead to 
all the data be in a single directory where pip packages are stored.
   
   Well, currently i either had to figure out which packages specifically the 
Python lib require to execute, or use the packages from systemds that was 
downloaded anyway. To keep it simple in development i chose the later option. I 
agree that one install command through pip would be better, but i also would 
like that we don't install, copy or download the jars twice.
   
   > Also setting up java is a single command (we should actually force java 8 
execution, which we don't do atm jus `java ...` right?).
   
   We need to move forward towards java 11. but not for this release: Hadoop 
3.x and Spark 3.x use/support Java 11.
