Subject G1GC vs ParallelGC
Date Wed, 20 Jun 2018 06:18:16 GMT
Hi guys,

I just wanted to know, why my ParallelGC (*--conf
"spark.executor.extraJavaOptions=-XX:+UseParallelGC"*) in a very long Spark
ML Pipeline works faster than when I set G1GC (*--conf
"spark.executor.extraJavaOptions=-XX:+UseG1GC"*), even though the Spark
community suggests G1GC to be much better than the ParallelGC.

Any pointers?

Thanks,
Aakash.
