TIF needs to be able to set scanner caching size for smaller row tables & performance
-------------------------------------------------------------------------------------

                 Key: HBASE-1576
                 URL: https://issues.apache.org/jira/browse/HBASE-1576
             Project: Hadoop HBase
          Issue Type: Bug
          Components: mapred
    Affects Versions: 0.20.0
            Reporter: ryan rawson
            Priority: Critical
             Fix For: 0.20.0


TIF goes with the default scanner caching size (1).  When each row is processed very fast
and is small, this limits the overall performance.  By setting a higher scanner caching level
you can achieve 100x+ the performance with the exact same map-reduce and table.
