> I was attempting to create hive tables over some partitioned Avro files. It 
> seems the void data type (Avro null) is not supported on partitioned tables 
> (i could not replicate the bug on an un-partitioned table).
> ---------------
> i managed to replicate the bug on two different hive versions.
> Hive 1.1.0-cdh5.10.0
> Hive 2.1.1-amzn-0
