Apache crunch unable to write output

Might be oversight but I am unable to spot why Apache Crunch won't write out output to a file for a very simple program I am writing to learn Crunch..

Here's the code:

import org.apache.crunch.Pipeline;
import org.apache.hadoop.conf.Configuration;    

....
private Pipeline                  pipeline;
private Configuration             etlConf;

....
this.etlConf  = getConf();
this.pipeline = new MRPipeline(TestETL.class, etlConf);
....

// Read file
logger.info("Reading input file: " + inputFileURI.toString());
PCollection<String> input = pipeline.readTextFile(inputFileURI.toString());

System.out.println("INPUT SIZE = " + input.asCollection().getValue().size());

// Write file 
logger.info("Writing Final output to file: " + outputFileURI.toString());
input.write(
    To.textFile(outputFileURI.toString()),
    WriteMode.OVERWRITE
);

This is the logging I see when I execute this jar using hadoop:

18/12/31 09:41:51 INFO etl.TestClass: Executing Test run
18/12/31 09:41:51 INFO etl.TestETL: Reading input file: /user/sw029693/process_analyzer/input/input.txt
INPUT SIZE = 3
18/12/31 09:41:51 INFO etl.TestETL: Writing Final output to file: 
/user/sw029693/process_analyzer/output/occurences
18/12/31 09:41:51 INFO impl.FileTargetImpl: Will write output files to new path: /user/sw029693/process_analyzer/output/occurences
18/12/31 09:41:51 INFO etl.TestETL: Cleaning-up TestETL run
18/12/31 09:41:51 INFO etl.TestETL: ETL completed with status 0.

The input file is very simple and looks like this:

this is line 1
this is line 2
this is line 3

Although the logging indicates a write should have happened to the output location, I see no files being created. Any thoughts?

Usage: Run as java program with arguments: 1st arg is input fileName or directory and the second arg is output file directory. The out filename is event-Timestamp and remember there is a single space between the args{0} & args{1}. /user/sw029693/process_analyzer/input/input.txt /user/sw029693/process_analyzer/input/
