fapifta commented on issue #710: HDDS-3173. Provide better default JVM options URL: https://github.com/apache/hadoop-ozone/pull/710#issuecomment-604118733 Thank you for addressing my concern, sounds reasonable, and I can accept the current solution. I agree that most of the users will have their own settings in a production environment and hopefully if someone starts to tune the JVM then he/she will know what to do. Still I think it would be good to document this behaviour, or at least emit a notification about the fact that we do not set the default GC options, as the patch does when the defaults are added, maybe we should do it the other way around, as if someone does not bother to set any option, then defaults are fine for that case, and if someone sets something we would like to let him/her know what would have been set, so he/she can review and preserve what is still needed. What do you think?
