main

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

Throws:

Exception

printUsage

protected void printUsage()

Description copied from class: TezExampleBase

Print usage instructions for this example

                     TezConfiguration tezConf,
                     TezClient tezClient)
              throws Exception

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
