>
> Key: AVRO-503
> URL: https://issues.apache.org/jira/browse/AVRO-503
> Project: Avro
> Issue Type: Bug
> Components: java, python
> Affects Versions: 1.3.2

> 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:
> {noformat}
> Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: -1
