Hi @dongjoon-hyun, I ran the above tests on a build from master. The test was run using AppleJDK-11.0.5.10.1. Did you export `SPARK_SUBMIT_OPTS="-XX:+AlwaysPreTouch --Xms=1g"` before starting spark-shell? The reason for this is that we want to "lock" in the amount of RSS that is taken up by the heap at the start of the process, then any further growth can be attributed to native libraries. Also the assumption was the default `--Xmx=1g` would be used. -- This is an automated message from the Apache Git Service.
