The Service Provider Interface for the Metrics API. This package provides
an interface allowing a variety of metrics reporting implementations to be
plugged in to the Metrics API. Examples of such implementations can be found
in the packages org.apache.hadoop.metrics.file and
org.apache.hadoop.metrics.ganglia.
Plugging in an implementation involves writing a concrete subclass of
AbstractMetricsContext. The subclass should get its
configuration information using the getAttribute(attributeName)
method.
