Description
In UnorderedInputConfig (https://github.com/apache/tez/blob/master/tez-runtime-library/src/main/java/org/apache/tez/runtime/library/conf/UnorderedKVInputConfig.java) some methods of SpecificBuilder have a parameterized return type (SpecificBuilder<E>) and some a non-parameterized return type (SpecificBuilder).
Shouldn't all methods return the parameterized version?
