[jira] [Commented] (ACCUMULO-695) Make input and output formats support the old mapreduce api again

    [ https://issues.apache.org/jira/browse/ACCUMULO-695?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13530387#comment-13530387 ] 

Christopher Tubbs commented on ACCUMULO-695:
--------------------------------------------

I would argue against doing it in the same classes, because I don't think users familiar with one and not the other, should be bombarded with available API methods that aren't suitable to the framework of their choice. Further, each framework has separate design goals, documentation, and examples, and it could be confusing to both developers and users to maintain these in a single set of classes.

> It might be possible to do this with single classes that support both, e.g.
> class InputFormatBase<K,V> extends InputFormat<K,V> implements org.apache.hadoop.mapred.InputFormat<K,V>.
