Common complaints I've heard about Oozie is that it has a high learning curve, not a great UI, and people hate the fact that it is XML based. This is a pretty decent comparison of Oozie vs Luigi (and Azkaban):
That presentation was pretty good with the good and bad takes. Do you think frameworks like Casacading or spark make things a lot easier as a higher abstraction on hadoop / different compute model?
I haven't tried Cascading, but I've started doing some stuff with Spark and really like it. I feel like it is usually an easier abstraction to work with and it is a lot easier to prototype and experiment with.
