Alright, I tested the latest code on a yarn cluster and verified that my
cluster scaled up and down according to the workload as expected. I'm merging
this. Thanks everyone for reviewing.
There will be a few follow up patches:
- SPARK-4134: Tone down scary messages when executors are removed as
expected
- SPARK-4136: Cancel outstanding requests if queue becomes empty
- SPARK-4138: Guard against incompatible settings on number of executors
(#3002)
- SPARK-4139: Start the number of executors at the max (also #3002)
- SPARK-4140: Document the configs
The last 3 are expected to block the 1.2 release while the rest are
nice-to-haves.
