Saikat, are you working on branch 0.20 instead of trunk? MultiFileWordCount in branch 0.20 does not work as far as I remember. You should work on trunk instead of branch 0.20, because HADOOP-6891 is an improvement and cannot go into 0.20 releases. See org.apache.hadoop.mapreduce.TestMapReduceLocal in MapReduce project which has a junit test running MultiFileWordCount.

I have written a Junit test suite using junit 4 that drives all the examples. This is currently working inside Eclipse and I will be moving this over to work from the main hadoop ant file. Almost all of the examples seem to be working fine, I noticed however that the MultiFileWordCount is throwing the following exception: WARNING: job_local_0001java.lang.ClassCastException: org.apache.hadoop.io.IntWritable cannot be cast to org.apache.hadoop.io.LongWritableBefore I investigate this further I was wondering if anyone else has run into this issue, is this example supposed to work right out of the box (provided of course that you give proper inputs)? In my case the inputs consist of files in the input directory and a destination output directory which gets autocreated by the code.Thanks in advance for your help. Regards
