Class AcidMetricService

java.lang.Object

org.apache.hadoop.hive.metastore.metrics.AcidMetricService

All Implemented Interfaces:

Runnable, org.apache.hadoop.conf.Configurable, MetastoreTaskThread

public class AcidMetricService
extends Object
implements MetastoreTaskThread

Collect and publish ACID and compaction related metrics. Everything should be behind 2 feature flags: MetastoreConf.ConfVars#METRICS_ENABLED and MetastoreConf.ConfVars#METASTORE_ACIDMETRICS_THREAD_ON.
