co.cask.cdap.data2.datafabric.dataset.service.executor

Class YarnDatasetOpExecutor

java.lang.Object

com.google.common.util.concurrent.AbstractIdleService

co.cask.cdap.common.service.UncaughtExceptionIdleService

co.cask.cdap.data2.datafabric.dataset.service.executor.RemoteDatasetOpExecutor

co.cask.cdap.data2.datafabric.dataset.service.executor.YarnDatasetOpExecutor

All Implemented Interfaces:

DatasetOpExecutor, com.google.common.util.concurrent.Service

public class YarnDatasetOpExecutor
extends RemoteDatasetOpExecutor

Starts DatasetOpExecutorService in YARN. TODO: Currently the DatasetOpExecutorService (which this communicates with) is started by MasterTwillApplication. We want to start the DatasetOpExecutorService in this class startUp(), but it's not possible currently since the service relies on MetricsClientRuntimeModules which is in watchdog module.
