I am trying to run Word Count on hadoop, but I am keep getting this error in eclipse. I have tried several things but does not seem to work.

Following is the error: 

log4j:ERROR setFile(null,true) call failed.

Hi@Raj,

I think you need to provide permission to the /ozone.log file. Check the file property and permission first. And give proper permission. Otherwise, you can try with the root user. It will work.
