## Uses of Interface
org.apache.hadoop.metrics.MetricsContext

Packages that use MetricsContext
org.apache.hadoop.metrics | Note, this package is deprecated in favor of `org.apache.hadoop.metrics2` usage.
org.apache.hadoop.metrics.file | Implementation of the metrics package that writes the metrics to a file.
org.apache.hadoop.metrics.ganglia | Implementation of the metrics package that sends metric data to Ganglia.
org.apache.hadoop.metrics.jvm |
org.apache.hadoop.metrics.spi | Note, this package is deprecated in favor of `org.apache.hadoop.metrics2` usage.

Uses of MetricsContext in org.apache.hadoop.metrics

Methods in org.apache.hadoop.metrics that return MetricsContext
`static MetricsContext` | `MetricsUtil.getContext(String contextName)` Deprecated.
`MetricsContext` | `ContextFactory.getContext(String contextName)` Deprecated.
`static MetricsContext` | `MetricsUtil.getContext(String refName, String contextName)` Deprecated. Utility method to return the named context.
`MetricsContext` | `ContextFactory.getContext(String refName, String contextName)` Deprecated. Returns the named MetricsContext instance, constructing it if necessary using the factory's current configuration attributes.
`static MetricsContext` | `ContextFactory.getNullContext(String contextName)` Deprecated. Returns a "null" context - one which does nothing.

Methods in org.apache.hadoop.metrics that return types with arguments of type MetricsContext
`Collection<MetricsContext>` | `ContextFactory.getAllContexts()` Deprecated. Returns all MetricsContexts built by this factory.

Methods in org.apache.hadoop.metrics with parameters of type MetricsContext
`static MetricsRecord` | `MetricsUtil.createRecord(MetricsContext context, String recordName)` Deprecated. Utility method to create and return new metrics record instance within the given context.
`void` | `Updater.doUpdates(MetricsContext context)` Deprecated. Timer-based call-back from the metric library.

Uses of MetricsContext in org.apache.hadoop.metrics.file

Classes in org.apache.hadoop.metrics.file that implement MetricsContext
`class` | `FileContext` Deprecated. use `FileSink` instead.

Uses of MetricsContext in org.apache.hadoop.metrics.ganglia

Classes in org.apache.hadoop.metrics.ganglia that implement MetricsContext
`class` | `GangliaContext` Deprecated. in favor of `org.apache.hadoop.metrics2` usage.
`class` | `GangliaContext31` Context for sending metrics to Ganglia version 3.1.x.

Uses of MetricsContext in org.apache.hadoop.metrics.jvm

Methods in org.apache.hadoop.metrics.jvm with parameters of type MetricsContext
`void` | `JvmMetrics.doUpdates(MetricsContext context)` Deprecated. This will be called periodically (with the period being configuration dependent).

Uses of MetricsContext in org.apache.hadoop.metrics.spi

Classes in org.apache.hadoop.metrics.spi that implement MetricsContext
`class` | `AbstractMetricsContext` Deprecated. in favor of `org.apache.hadoop.metrics2` usage.
`class` | `CompositeContext` Deprecated. in favor of `org.apache.hadoop.metrics2` usage.
`class` | `NoEmitMetricsContext` Deprecated. in favor of `org.apache.hadoop.metrics2` usage.
`class` | `NullContext` Deprecated. in favor of `org.apache.hadoop.metrics2` usage.
`class` | `NullContextWithUpdateThread` Deprecated. in favor of `org.apache.hadoop.metrics2` usage.
