[SPARK-17920] HiveWriterContainer passes null configuration to serde.initialize, causing NullPointerException in AvroSerde when using avro.schema.url - ASF JIRA

Details

Type: Bug
Status: Resolved
Priority: Minor
Resolution: Fixed
Affects Version/s: 1.6.2, 2.0.0
Fix Version/s: 2.2.1, 2.3.0
Component/s: SQL
Labels:
None
Environment:

AWS EMR 5.0.0: Spark 2.0.0, Hive 2.1.0

Target Version/s:

2.2.1, 2.3.0

Description

When HiveWriterContainer intializes a serde it explicitly passes null for the Configuration:

https://github.com/apache/spark/blob/v2.0.0/sql/hive/src/main/scala/org/apache/spark/sql/hive/hiveWriterContainers.scala#L161

When attempting to write to a table stored as Avro with avro.schema.url set, this causes a NullPointerException when it tries to get the FileSystem for the URL:

https://github.com/apache/hive/blob/release-2.1.0-rc3/serde/src/java/org/apache/hadoop/hive/serde2/avro/AvroSerdeUtils.java#L153

Reproduction:

spark-sql> create external table avro_in (a string) stored as avro location '/avro-in/' tblproperties ('avro.schema.url'='/avro-schema/avro.avsc');

spark-sql> create external table avro_out (a string) stored as avro location '/avro-out/' tblproperties ('avro.schema.url'='/avro-schema/avro.avsc');

spark-sql> select * from avro_in;
hello
Time taken: 1.986 seconds, Fetched 1 row(s)

spark-sql> insert overwrite table avro_out select * from avro_in;
