Description

When I run a file that first creates an Avro table using the Avro SerDe, then immediately creates an LZO text table and inserts data into the LZO table, the resulting LZO table contain Avro data files. When I remove the Avro CREATE TABLE statement, the LZO table contains .lzo files as expected.

DROP TABLE IF EXISTS avro_table;
CREATE EXTERNAL TABLE avro_table
ROW FORMAT SERDE 'org.apache.hadoop.hive.serde2.avro.AvroSerDe'
STORED AS
INPUTFORMAT 'org.apache.hadoop.hive.ql.io.avro.AvroContainerInputFormat'

TBLPROPERTIES ('avro.schema.literal' = '{
"namespace": "testing.hive.avro.serde",
"name": "test_record",
"type": "record",

{"name":"int1", "type":"long"},
{"name":"string1", "type":"string"}
]
}');
