Zhihui created SPARK-1946:
-----------------------------
Summary: Submit stage after executors have been registered
Key: SPARK-1946
URL: https://issues.apache.org/jira/browse/SPARK-1946
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 1.0.0
Reporter: Zhihui
Because creating TaskSetManager and registering executors are asynchronous, in
most situation, early stages' tasks run without preferred locality.
A simple solution is sleeping few seconds in application, so that executors
have enough time to register.
A better way is to make DAGScheduler submit stage after a few of executors have
been registered by configuration properties.
# submit stage only after successfully registered executors arrived the ratio,
default value 0
spark.executor.registeredRatio = 0.8
# whatever registeredRatio is arrived, submit stage after the
maxRegisteredWaitingTime(millisecond), default value 10000
spark.executor.maxRegisteredWaitingTime = 5000
