> final Pipeline pipeline = new SparkPipeline("local", "crunchhbase", HBaseInputSource.class,
conf);
>         final PTable<ImmutableBytesWritable, Result> read = pipeline.read(new HBaseSourceTarget("t1",
new Scan()));
> return an empty table, while it works with MRPipeline.
> root cause is the combination of sparks getJavaRDDLike method:
> source.configureSource(job, -1);
>       Converter converter = source.getConverter();
>       JavaPairRDD<?, ?> input = runtime.getSparkContext().newAPIHadoopRDD(
>           job.getConfiguration(),
>           CrunchInputFormat.class,
>           converter.getKeyClass(),
>           converter.getValueClass());
> That assumes "CrunchInputFormat.class" (and always uses -1)
> and hbase configureSoruce method:
> if (inputId == -1) {
>       job.setMapperClass(CrunchMapper.class);
>       job.setInputFormatClass(inputBundle.getFormatClass());
>       inputBundle.configure(conf);
>     } else {
>       Path dummy = new Path("/hbase/" + table);
>       CrunchInputs.addInputPath(job, dummy, inputBundle, inputId);
>     }
> easiest solution I see, is always calling CrunchInputs.addInputPath, in every source.
