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

to
tie Spark to Accumulo (for both fetching data and dumping results)?
