      Description

      Our mapred implementation is pretty meager compared to the code in mapreduce. Notably, it does not support a user-provided Scan instance for mapreduce jobs run over hbase tables. The only thing we offer is column family filtering. For applications to support predicate pushdown and enjoy efficient HBase access, either they transition their entire codebase over to mapreduce, or we offer this functionality.
