Keegan Mosley updated HIVE-3095:
--------------------------------
Description:
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';
