> There are three LocationStrategy: PreferBrokers, PreferConsistent,
> PreferFixed. I got a scenario that I need a random one. There are plenty of
> topic partitions that are varies from each other with different records
> inside. And I have a lot of executors. PreferBrokers does not help here.
> PreferConsistent will make things worse that some executor will always get
> heavy tasks. PreferFixed does not help too, because it is fixed, neither to
> say I have to create a mapping manually.
> A random LocationStrategy should dispatch a topic partition to different
> executors in different window. This would balance the load among spark
> executors.
