runJob

protected final int runJob(String[] args,
         org.apache.tez.dag.api.TezConfiguration tezConf,
         org.apache.tez.client.TezClient tezClient)
                    throws org.apache.tez.dag.api.TezException,
                           InterruptedException,
                           IOException

Description copied from class: TezExampleBase

Create and execute the actual DAG for the example

Specified by:

runJob in class TezExampleBase

Parameters:

args - arguments for execution

tezConf - the tez configuration instance to be used while processing the DAG

tezClient - the tez client instance to use to run the DAG if any custom monitoring is required. Otherwise the utility method TezExampleBase.runDag(org.apache.tez.dag.api.DAG, boolean, org.apache.commons.logging.Log) should be used

Returns:

Zero indicates success, non-zero indicates failure

Throws:

org.apache.tez.dag.api.TezException

IOException

InterruptedException

printUsage

Description copied from class: TezExampleBase

Print usage instructions for this example

Specified by:

printUsage in class TezExampleBase

validateArgs

protected final int validateArgs(String[] otherArgs)

Description copied from class: TezExampleBase

Validate the arguments

Specified by:

validateArgs in class TezExampleBase

Parameters:

otherArgs - arguments, if any

Returns:

Zero indicates success, non-zero indicates failure

main

public static void main(String[] args)
                 throws Exception

Throws:
