Review request for geode, Anthony Baker, Hitesh Khamesra, Udo Kohlmeyer, and Dan Smith. Repository: geode Description ------- Looking through our distributedTest output I see a large number of full GCs initiated by Metaspace cleanup. Some of these GCs are taking as long as 70 seconds and cause nodes to be kicked out of the distributed system. For Java 8 it's recommended that you estimate requirements for Metaspace and set XXMetaspaceSize to avoid these full GCs. Our REST tests seem to need nearly half a gigabyte of metaspace so I've set it accordingly. An AWS precheckin run with this change showed only one GC initiated by metaspace management, in the geode-web distributedTest suite lasting 1/2 second.
