Ryan Blue created SPARK-16382: --------------------------------- Summary: YARN - Dynamic allocation with spark.executor.instances should increase max executors. Key: SPARK-16382 URL: https://issues.apache.org/jira/browse/SPARK-16382 Project: Spark Issue Type: Bug Components: YARN Reporter: Ryan Blue
SPARK-13723 changed the behavior of dynamic allocation when {{--num-executors}} ({{spark.executor.instances}}) is set. Rather than turning off dynamic allocation, the value is used as the initial number of executors. This did not change the behavior of {{spark.dynamicAllocation.maxExecutors}}. We've noticed that some users set {{--num-executors}} higher than the max and the expectation is that the max increases. I think that either max should be increased, or Spark should fail and complain that the executors requested is higher than the max. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
