> Per MAPREDUCE-6166, both InMemoryMapOutput and OnDiskMapOutput will be doing similar
things with regards to IFile streams.
> In order to make it explicit that InMemoryMapOutput and OnDiskMapOutput are different
from 3rd-party implementations, this JIRA will make them subclass a common class (see https://issues.apache.org/jira/browse/MAPREDUCE-6166?focusedCommentId=14223368&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14223368)
