If Owl is run on an edge node on a popular hadoop distribution such as HDP, CDH, EMR it will automatically register the jobs with Yarn Resource Manager.
Owl can also run using spark master by using the -master input and passing in spark:url
Owl can run in standalone most but naturally will not distribute the processing beyond the hardware it was activated on.
