---------------------------------
About the results by QA.
How can I find which core test was failing? in my local machine, all tests
under hadoop-common were passed. My class is not used by other code yet.
[~manukranthk] how do you find the java warnings?
mvn findbugs:findbugs -X shows two warnings are not realted to my code.
