Hi Spark Experts,
Today I tried Spark 2.0 on YARN and also enabled Dynamic Resource Allocation feature, I just find that no matter I specify --num-executor in spark-submit command or not, the Dynamic Resource Allocation is used, but I remember when I specify --num-executor option in spark-submit command in Spark 1.6, the Dynamic Resource Allocation feature will not be used/effect for that job. And I can see below log in Spark 1.6 . Is this a behavior change in Spark 2.0? And How can I disable Dynamic Resource Allocation for a specific job submission temporarily as before?
