In SQL it is impossible to specify map > type for example because SQL DDL parser can handle struct type only. Need to > support schemas in JSON format as it has been already implemented > [there|https://github.com/apache/spark/blob/branch-2.3/sql/core/src/main/scala/org/apache/spark/sql/functions.scala#L3225-L3229]: > {code:scala} > val dataType = try { > DataType.fromJson(schema) > } catch { > case NonFatal(_) => StructType.fromDDL(schema) > } > {code} -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
