-----------------------------------
Summary: Self-referencing Avro schema creates infinite loop on
table creation
Key: HIVE-3095
URL: https://issues.apache.org/jira/browse/HIVE-3095
Project: Hive
Issue Type: Bug
Components: Serializers/Deserializers
Affects Versions: 0.9.1
Reporter: Keegan Mosley
Priority: Minor
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
]
}
');
