Abhishek Kapoor commented on HADOOP-8834:
-----------------------------------------
Since this is my first time fixing jira issue in open source. And this would
easy to fix enhancment.
Could anyone please guide or mentor me in fixing process of the issue, for
example which branch i need to check out and how to create patch for the same.
Also do i need a test case for this minor issue.
Any help would be really appreciated and would lead me to know the process, so
that I can contribute more in the community.
Many Thanks
Abhishek
