When you arrive at the restaurant, there will usually be signage telling you where delivery orders can be picked up. The used and committed size of the returned memory usage is the sum of those values of all heap memory pools whereas the init and max size of the returned memory usage represents the setting of the heap memory which may not be the sum of those of all heap memory pools. Nothing else has been touched in 3 MONTHS. Elapsed total minor GC time. Peak memory that the JVM is using for direct buffer pool (, Peak memory that the JVM is using for mapped buffer pool (. Timers, meters and histograms are annotated parameter names are composed by the prefix spark.metrics.conf. if the history server is accessing HDFS files on a secure Hadoop cluster. plugins are ignored. spark.history.fs.driverlog.cleaner.enabled. at $SPARK_HOME/conf/metrics.properties.
