Overrides:

serviceInit in class org.apache.hadoop.service.AbstractService

Throws:

java.lang.Exception

serviceStart

protected void serviceStart()
                     throws java.lang.Exception

Overrides:

serviceStart in class org.apache.hadoop.service.AbstractService

Throws:

java.lang.Exception

serviceStop

protected void serviceStop()
                    throws java.lang.Exception

Overrides:

Throws:

java.lang.Exception

addApplicationIfAbsent

public boolean addApplicationIfAbsent(org.apache.hadoop.yarn.api.records.ApplicationId appId,
                                      java.lang.String user)

Creates and adds an app level collector for the specified application id. The collector is also initialized and started. If the service already exists, no new service is created.

Parameters:

appId - Application Id to be added.

user - Application Master container user.

Returns:

whether it was added successfully

removeApplication

public boolean removeApplication(org.apache.hadoop.yarn.api.records.ApplicationId appId)

Removes the app level collector for the specified application id. The collector is also stopped as a result. If the collector does not exist, no change is made.

Parameters:

appId - Application Id to be removed.

Returns:

whether it was removed successfully

initializeContainer

public void initializeContainer(org.apache.hadoop.yarn.server.api.ContainerInitializationContext context)

Creates and adds an app level collector for the specified application id. The collector is also initialized and started. If the collector already exists, no new collector is created.

Overrides:

initializeContainer in class org.apache.hadoop.yarn.server.api.AuxiliaryService

stopContainer

public void stopContainer(org.apache.hadoop.yarn.server.api.ContainerTerminationContext context)

Removes the app level collector for the specified application id. The collector is also stopped as a result. If the collector does not exist, no change is made.

Overrides:

stopContainer in class org.apache.hadoop.yarn.server.api.AuxiliaryService

removeApplicationCollector
