Right, we’ve been trying this with little luck — largely because I get the
error:
Caused by: java.lang.ClassCastException:

Code:

OrcFileSource<Verint1978Record>(new Path(inputPath),
Orcs.reflects(Verint1978Record.class));
PCollection<Verint1978Record> persons = pipeline.read(source);

Here's the java excerpt from that article to read into Avro class (I'm
assuming).
[code language=”Java”]
// Read an ORCFile using reflection-based serialization (slowest):
OrcFileSource<Person> source = new OrcFileSource<Person>(new Path(inputPath), \
Orcs.reflection(Person.class));
PCollection<Person> persons = pipeline.read(source);

Crunch Gurus,
What is the Crunch-convenient or recommended way to read the contents of a Hive

Thanks!
