> To reproduce this error, take two fields in an avro schema document matching the following:
> "type" : { "type": "array", "items": [ "null", { "type": "map", "values": [ "null", "string" ] } ] }
> "type" : { "type": "map", "values": [ "null" , { "type": "array", "items": [ "null" , "string"] } ] }
> After creating two tables in hive with these schemas, the describe statement on each of them will only return the schema for the first one loaded. This is due to a hashCode() collision in the InstanceCache.
> A patch will be included in this ticket shortly which removes the hashCode call from the InstanceCache's internal HashMap, and instead provides the entire schema object.
