----------------------------------
Attachment: avro_data
avro.avsc
> 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: 1.6.2, 2.0.0
> Environment: AWS EMR 5.0.0: Spark 2.0.0, Hive 2.1.0
> Reporter: James Norvell
> Priority: Minor
> Attachments: avro.avsc, avro.avsc, avro_data, avro_data
>
>
> 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;
