[jira] [Created] (SPARK-17920) HiveWriterContainer passes null
configuration to serde.initialize, causing NullPointerException in
AvroSerde when using avro.schema.url
James Norvell created SPARK-17920:
-------------------------------------
Summary: HiveWriterContainer passes null configuration to serde.initialize, causing NullPointerException in AvroSerde when using avro.schema.url
Key: SPARK-17920
URL: https://issues.apache.org/jira/browse/SPARK-17920
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.0.0, 1.6.2
Environment: AWS EMR 5.0.0: Spark 2.0.0, Hive 2.1.0
Reporter: James Norvell
Priority: Minor
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:
{noformat}
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;
