------------------------------------
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

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?
