------------------------------------
Assignee: Arun Mahadevan
> Fix namespace handling in SchemaConverters.toAvroType
> -----------------------------------------------------
>
> Key: SPARK-25260
> URL: https://issues.apache.org/jira/browse/SPARK-25260
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.4.0
> Reporter: Arun Mahadevan
> Assignee: Arun Mahadevan
> Priority: Major
> Fix For: 2.4.0
>
>
> `toAvroType` converts spark data type to avro schema. It always appends the
> record name to namespace so its impossible to have an Avro namespace
> independent of the record name.
>
> When invoked with a spark data type like,
>
> {code:java}
> val sparkSchema = StructType(Seq(
> StructField("name", StringType, nullable = false),
> StructField("address", StructType(Seq(
> StructField("city", StringType, nullable = false),
> StructField("state", StringType, nullable = false))),
> nullable = false)))
>
> // map it to an avro schema with top level namespace "foo.bar",
> val avroSchema = SchemaConverters.toAvroType(sparkSchema, false, "employee",
> "foo.bar")
> // result is
> // avroSchema.getName = employee
> // avroSchema.getNamespace = foo.bar.employee
> // avroSchema.getFullname = foo.bar.employee.employee
>
> {code}
>
