SaintBacchus created SPARK-8119:
-----------------------------------
Summary: Spark will set total executor when some executors fail.
Key: SPARK-8119
URL: https://issues.apache.org/jira/browse/SPARK-8119
Project: Spark
Issue Type: Bug
Components: Scheduler
Affects Versions: 1.4.0
Reporter: SaintBacchus
Fix For: 1.4.0
DynamicAllocation will set the total executor to a little number when it wants
to kill some executors.
But in no-DynamicAllocation scenario, Spark will also set the total executor.
So it will cause thus problem: sometimes an executor fails down, there is no
more executor which will be pull up by spark.
