Accumulo and Spark

[Megavolt <jb...@42six.com>]

I've been doing some Googling and haven't found much info on how to
incorporate Spark and Accumulo.  Does anyone know of some examples of how to
tie Spark to Accumulo (for both fetching data and dumping results)?

It's very straightforward to set up a Hadoop RDD to use
AccumuloInputFormat. Something like this will do the trick:

private JavaPairRDD<Key,Value> newAccumuloRDD(JavaSparkContext sc,
AgileConf agileConf, String appName, Authorizations auths)
        throws IOException, AccumuloSecurityException {
    Job hadoopJob = Job.getInstance(agileConf, appName);
    // configureAccumuloInput is exactly the same as for an MR job
    // sets zookeeper instance, credentials, table name, auths etc.
    configureAccumuloInput(hadoopJob, ACCUMULO_TABLE, auths);
    return sc.newAPIHadoopRDD(hadoopJob.getConfiguration(),
AccumuloInputFormat.class, Key.class, Value.class);
}

There's tons of docs around how to operate on a JavaPairRDD. But you're
right, there's hardly anything at all re. how to plug accumulo into spark.
