Ken Williams updated MRUNIT-215:
--------------------------------
    Description: 
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();

{code}

This is using MRUnit 1.1.0, but I got the same results with 1.0.0.  Looking in the MRUnit
code, it doesn't look like the {{MapDriverBase.mapInputPath}} member variable actually gets
used anywhere.
