在Hadoop Mapreduce中将行输出到Cassandra

Question

I would like to write a row back to Cassandra in my Reducer and am following two word count examples provided by Cassandra ( an example using cql3 and an example using Mutation ), but they are both outputing a single column given a key. Can I know how to output a row (ie, multiple columns) with a known key in a Reducer using either cql3 or Mutation?

Answer 1

You need to look at

CqlConfigHelper.setOutputCql

which you can use with a CQL string that has multiple replacements in it. This is detailed here:
