You should not put the application jar itself on the hdfs (in this case
hadoop-*-examples.jar).
If you run the following command, <in> and <out> are directories on the
configured filesystem (which is DFS most of the times):
bin/hadoop jar hadoop-*-examples.jar wordcount <in> <out>

Hi,
While running the WordCount.java file from hadoop, faced the following error:
Exception in thread "main" java.io.IOException: Error opening job jar:

Here the hdfs directory is : /user/droy/wordcount_hdfs/
Please advise.
