Hello, I've set spark.deploy.spreadOut=false in spark-env.sh.
> export SPARK_MASTER_OPTS="-Dspark.deploy.defaultCores=4 > -Dspark.deploy.spreadOut=false" There are 3 workers each with 4 cores. Spark-shell was started with noof cores = 6. Spark UI show that one executor was used with 6 cores. Is this a bug? This is with Spark 1.4. [image: Inline image 1] Srikanth
