[jira] [Created] (SPARK-8088) ExecutionAllocationManager spamming INFO logs about "Lowering target number of executors"

Ryan Williams created SPARK-8088:
------------------------------------

             Summary: ExecutionAllocationManager spamming INFO logs about "Lowering target number of executors"
                 Key: SPARK-8088
                 URL: https://issues.apache.org/jira/browse/SPARK-8088
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 1.3.1, 1.4.0
            Reporter: Ryan Williams


I am running a {{spark-shell}} built at 1.4.0-rc4, with:

{code}
  --conf spark.dynamicAllocation.enabled=true \
  --conf spark.dynamicAllocation.minExecutors=5 \
  --conf spark.dynamicAllocation.maxExecutors=300 \
  --conf spark.dynamicAllocation.schedulerBacklogTimeout=3 \
  --conf spark.dynamicAllocation.executorIdleTimeout=600 \
{code}

I can't really type any commands because I am getting 10 of these per second:

{code}
15/06/03 20:49:09 INFO spark.ExecutorAllocationManager: Lowering target number of executors to 5 because not all requests are actually needed (previously 5)
15/06/03 20:49:09 INFO spark.ExecutorAllocationManager: Lowering target number of executors to 5 because not all requests are actually needed (previously 5)
15/06/03 20:49:09 INFO spark.ExecutorAllocationManager: Lowering target number of executors to 5 because not all requests are actually needed (previously 5)
15/06/03 20:49:09 INFO spark.ExecutorAllocationManager: Lowering target number of executors to 5 because not all requests are actually needed (previously 5)
15/06/03 20:49:09 INFO spark.ExecutorAllocationManager: Lowering target number of executors to 5 because not all requests are actually needed (previously 5)
15/06/03 20:49:09 INFO spark.ExecutorAllocationManager: Lowering target number of executors to 5 because not all requests are actually needed (previously 5)
{code}

It should not print anything if it is not in fact lowering the number of executors / is already at the minimum, right?
