squito commented on issue #24132: [SPARK-27189][CORE] Add Executor metrics and memory usage instrumentation to the metrics system URL: https://github.com/apache/spark/pull/24132#issuecomment-558272217 > do you have any opinioins on the default value for METRICS_EXECUTORMETRICS_SOURCE_ENABLED ? since I don't really use the metrics system much myself, I don't really have a strong opinion. How important is it to keep the set of exported metrics small (for load on the metrics collection agent / clutter on the display?) I think I'd probably put it on by default but want to hear your thoughts
