Two things to check
1) The jar file should be on the local disk and not on the DFS. It looks 
like 'usr/hemal/wordconut.jar' is the dfs path. So the command would 
look like
bin/hadoop jar /local/path/to/jar/job.jar args
So if you have the jar file in your home folder then you can use 
~/job.jar or /home/user-name/job.jar
2) Also make sure its wordconut.jar and not wordcount.jar
