Josh Wills updated CRUNCH-572:
------------------------------
    Attachment: CRUNCH-572.patch

[~aeckstein] here's a patch to fix this for all tuple types, not just pairs (e.g., Avros.trips(PTableType, PTableType, FooType) would break as well.)

> The Avros.tableOf() method produces a record schema named "org.apache.avro.mapred.Pair", which cannot be unique across types, whereas the Avros.pairs() method similarly creates a record schema, but calls Avros.createTupleSchema() which creates a unique name at every call.
> Example that fails on constructing schema:
> AvroType<Pair<String, String>> t1 = Avros.tableOf(Avros.strings(), Avros.strings());
> AvroType<Pair<String, Double>> t2 = Avros.tableOf(Avros.strings(), Avros.doubles());
> AvroType<Pair<Pair<String, String>, Pair<String, Double>>> t3 = Avros.pairs(t1, t2);
> System.out.println("schema: " + t3.getSchema().toString());
> Can the tableOf() method be updated to call the createTupleSchema() method instead of the avro pair constructor?
