--------------------------------------
Summary: Optimize the schedule procedure in Master
Key: SPARK-3411
URL: https://issues.apache.org/jira/browse/SPARK-3411
Project: Spark
Issue Type: Improvement
Components: Deploy
Reporter: WangTaoTheTonic
Priority: Minor
If the waiting driver array is too big, the drivers in it will be dispatched to
the first worker we get(if it has enough resources), with or without the
Randomization.
We should do randomization every time we dispatch a driver, in order to better
balance drivers.
