what to use in place of mrunit withInputValue deprecated

Question

I am using MRUnit to test Map Reduce code. I can't use .withInputValue as it is deprecated. I could not locate an equivalent that works. setInputValue does not work either. What is the work-around?

Answer 1

Use withInput(). Exmaple (this. is with mrunit-1.0.0-hadoop2.jar )

MapDriver<LongWritable,Text,Text,IntWritable> mapDriver;
...
mapDriver.withInput(new LongWritable(), new Text("some line of text));
mapDriver.withOUtput(new Text("some key)); new IntWritable(..));
mapDriver.runTest();

Here's the maven dependency. Note the Hadoop2 classifier.

<dependency>
    <groupId>org.apache.mrunit</groupId>
    <artifactId>mrunit</artifactId>
    <version>1.0.0</version>
    <classifier>hadoop2</classifier>
</dependency>
