> An Avro schema which has a field reference to itself will create an infinite loop which eventually throws a StackOverflowError.
> To reproduce using the linked-list example from http://avro.apache.org/docs/1.6.1/spec.html
> create table linkedListTest row format serde 'org.apache.hadoop.hive.serde2.avro.AvroSerDe'
> with serdeproperties ('avro.schema.literal'='
> {
>    "type": "record", 
>    "name": "LongList",
>    "aliases": ["LinkedLongs"],                      // old name for this
>    "fields" : [
>       {"name": "value", "type": "long"},             // each element has a long
>       {"name": "next", "type": ["LongList", "null"]} // optional next element
>    ]
> }
> ')
> stored as inputformat 'org.apache.hadoop.hive.ql.io.avro.AvroContainerInputFormat'
> outputformat 'org.apache.hadoop.hive.ql.io.avro.AvroContainerOutputFormat';
