Re: [G1GC] -XX: -ResizePLAB How to provide in Spark Submit
As typical `JAVA_OPTS` you need to pass as a single parameter: --conf "spark.executor.extraJavaOptions=-XX:+UseG1GC -XX:-ResizePLAB" Also you got an extra space in the parameter, there should be no space after the colon symbol On Tue, Jul 3, 2018 at 3:01 AM Aakash Basu wrote: > > Hi, > > I used the below in the Spark Submit for using G1GC - > > --conf "spark.executor.extraJavaOptions=-XX:+UseG1GC" > > Now, I want to use -XX: -ResizePLAB of the G1GC to control to avoid > performance degradation caused by a large number of thread communications. > > How to do it?
