> When using LIFO execution order, Oozie should run the latest READY action first. This includes when you start your Coordinator in the past, and Oozie plays "catch-up". However, Oozie will materialize 12 actions (the default), but will do @1 and then do the LIFO behavior (i.e. @12, @11, etc). This is likely due to a race condition about when the other actions are materialized/READY vs when Oozie checks to run an action, as the actions are materialized in FIFO order.

> The Coordinator was super simple. It was set to LIFO, and was running a workflow with a Shell action that would run sleep with an argument of 10 seconds.
