Use WritableComparable / Writable in RecordReader -------------------------------------------------
Key: CASSANDRA-4105 URL: https://issues.apache.org/jira/browse/CASSANDRA-4105 Project: Cassandra Issue Type: Wish Components: Hadoop Affects Versions: 0.8.11, 1.0.9, 1.1.1, 1.2 Reporter: Patrik Modesto Cassandra uses ByteByffer/List<Mutation> as key/value in RecordWriter. This prevents the use of MultipleOutputs class that requires a key to be WritableComparable and value to be Writable. MultipleOutputs is a very handy class that provides a way to write to several differrent OutputFormats from a reducer. In our case I have a mapreduce job that produces two results which I need to write to Cassandra and to a file respectively and as for now I need to run that mapreduce twice which is quite expensive. -- This message is automatically generated by JIRA.
