[jira] [Created] (SPARK-1946) Submit stage after executors have been registered

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
