Filter out ColumnFamily rows that aren't part of the query (using a IndexClause)
--------------------------------------------------------------------------------

                 Key: CASSANDRA-2878
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-2878
             Project: Cassandra
          Issue Type: New Feature
          Components: Hadoop
            Reporter: Mck SembWever
            Assignee: Mck SembWever
            Priority: Minor
             Fix For: 1.0


Currently, when running a MapReduce job against data in a Cassandra data store, it reads through
all the data for a particular ColumnFamily.  This could be optimized to only read through
those rows that have to do with the query.

It's a small change but wanted to put it in Jira so that it didn't fall through the cracks.
