Subject [jira] [Created] (MRUNIT-215) setMapInputPath() doesn't serve any purpose?

Ken Williams created MRUNIT-215:
-----------------------------------

             Summary: setMapInputPath() doesn't serve any purpose?
                 Key: MRUNIT-215
                 URL: https://issues.apache.org/jira/browse/MRUNIT-215
             Project: MRUnit
          Issue Type: Bug
    Affects Versions: 1.0.0, 1.1.0
            Reporter: Ken Williams


If I call {{MapDriver.setMapInputPath(...)}} in my test code, it seems to have no effect,
and the specified path doesn't get added to the input for the mapper.  Example:

{code}
import org.apache.hadoop.mrunit.mapreduce.MapDriver;
...
MapDriver<LongWritable, Text, Text, Text> mapDriver = MapDriver.newMapDriver(new myMapper());
mapDriver.setMapInputPath(new Path("my/data/path"));
mapDriver.run();

java.lang.IllegalStateException: No input was provided
