Uses of MetricsSource in org.apache.hadoop.fs.impl

Classes in org.apache.hadoop.fs.impl that implement MetricsSource

Modifier and Type	Class	Description
class	WeakRefMetricsSource	A weak referenced metrics source which avoids hanging on to large objects if somehow they don't get fully closed/cleaned up.

Methods in org.apache.hadoop.fs.impl that return MetricsSource

Modifier and Type	Method	Description
MetricsSource	WeakRefMetricsSource.getSource()	Get the source, will be null if the reference has been GC'd

Constructors in org.apache.hadoop.fs.impl with parameters of type MetricsSource

Modifier	Constructor	Description
	WeakRefMetricsSource(String name, MetricsSource source)	Constructor.

Uses of MetricsSource in org.apache.hadoop.ipc

Classes in org.apache.hadoop.ipc that implement MetricsSource

Modifier and Type	Class	Description
class	DecayRpcScheduler	The decay RPC scheduler tracks the cost of incoming requests in a map, then decays the costs at a fixed time interval.
static final class	DecayRpcScheduler.MetricsProxy	MetricsProxy is a singleton because we may init multiple schedulers and we want to clean up resources when a new scheduler replaces the old one.
