Tsuyoshi Ozawa commented on HADOOP-12378:
-----------------------------------------
{code}
the patch removes protected fields in abstract class
{code}
In this case, DataJoinMapperBase class is a public class which assumes to be
extended. These fields are useful from MapReduce jobs, so we can say the
warnings are false-positive. For the reason, we can ignore the warning here.
Could you update to create findbugs-exclude.xml?
