Stefan De Smit commented on CRUNCH-572:
---------------------------------------
We have a similar problem, where we used Pair.getPairSchema() in our own code
(so, outside of PTableType)
Isn't the problem that Pair.makePairSchema always uses the same name "Pair" for
different schema's (as there's a cache for same key/value schema) instead of
generating a new name similar to Avros.createTupleSchema
> Avro schema error in Avros.tableOf() can't redefine
> org.apache.avro.mapred.Pair
> -------------------------------------------------------------------------------

> Issue Type: Bug
> Affects Versions: 0.13.0

> Attachments: CRUNCH-572.patch

>
> 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?
