Enable map reduce to use indexes for ColumnFamilyInputFormat
------------------------------------------------------------
Key: CASSANDRA-2245
URL: https://issues.apache.org/jira/browse/CASSANDRA-2245
Project: Cassandra
Issue Type: Improvement
Components: Hadoop
Affects Versions: 0.7.2
Environment: Cassandra 0.7 or later and Hadoop 0.20.1 or later
Reporter: Matt Kennedy
Priority: Minor
Fix For: 0.8
Enable the ability to run a MapReduce job that takes a value in an indexed
column as a parameter, and use that to select the data that the MapReduce job
operates on. Right now, it looks like this isn't possible because
org.apache.cassandra.hadoop.ColumnFamilyRecordReader will only fetch data with
get_range_slices, not get_indexed_slices.
