Review request for Ambari and Dmytro Grinenko. Bugs: AMBARI-16691 https://issues.apache.org/jira/browse/AMBARI-16691 Repository: ambari Description ------- In ATLAS-616, we uncovered problems with Atlas web service when testing queries at scale. The investigation revealed a fix possible with tuning some GC parameters. Since this is environment specific, the fix in ATLAS-616 does not make the GC values default, but only suggests them in documentation. However, for HDP, we may want to default these settings in Ambari. Opening this JIRA to track the changes.
