Major Description
I'm attempting to add an avro equivalent to Cassandra's batch_mutate() method (thrift def here: https://svn.apache.org/repos/asf/cassandra/trunk/interface/cassandra.thrift). This is the first time I've attempted to nest maps within maps, and I'm assuming it's related since that seems like the only difference to the working examples I have.
Attached is a tarball that includes the protocol I'm using along with java and python examples (src/BatchMutate.java and py/batch_mutate.py) that reproduce the exceptions I'm seeing.
Running the java example produces:
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: -1 at org.apache.avro.io.parsing.Symbol$Alternative.getSymbol(Symbol.java:364) at org.apache.avro.io.ResolvingDecoder.doAction(ResolvingDecoder.java:191) at org.apache.avro.io.parsing.Parser.advance(Parser.java:88) at org.apache.avro.io.ResolvingDecoder.readIndex(ResolvingDecoder.java:168) at org.apache.avro.generic.GenericDatumReader.read(GenericDatumReader.java:81) at org.apache.avro.generic.GenericDatumReader.readRecord(GenericDatumReader.java:105) at org.apache.avro.generic.GenericDatumReader.read(GenericDatumReader.java:77) at org.apache.avro.generic.GenericDatumReader.read(GenericDatumReader.java:70) at org.apache.avro.ipc.Requestor.readHandshake(Requestor.java:181) at org.apache.avro.ipc.Requestor.request(Requestor.java:116) at org.apache.avro.specific.SpecificRequestor.invoke(SpecificRequestor.java:52) at $Proxy0.batch_mutate(Unknown Source) at BatchMutate.main(BatchMutate.java:43)
Running the python examples produces:
