[SPARK-11212][Core][Streaming]Make preferred locations support
ExecutorCacheTaskLocation and updateâ¦
⦠ReceiverTracker and ReceiverSchedulingPolicy to use it
This PR includes the following changes:
1. Add a new preferred location format, `executor_<host>_<executorID>`
(e.g., "executor_localhost_2"), to support specifying the executor locations
for RDD.
2. Use the new preferred location format in `ReceiverTracker` to optimize
the starting time of Receivers when there are multiple executors in a host.
