Issue with Apache Hudi and MoR snapshot tables


I just want to re-raise an issue we've been seeing for a long time, preventing us from querying Hudi MoR realtime tables using AWS Athena.

AWS Athena snapshot queries fails if there are two or more record array fields in a Hudi MoR table:

HIVE_CANNOT_OPEN_SPLIT: Error opening Hive split s3://prod-signal-data-platform-spark-experiments/temporary/articles_hudi_merge_on_read_dev/story_published_partition_date=2022-04-29/75f5af94-8369-4b04-b850-421826ef48cc-0_24-38-3759_20220506091903372.parquet (offset=33554432, length=33554432) using org.apache.hudi.hadoop.realtime.HoodieParquetRealtimeInputFormat: Can't redefine: array This query ran against the "articles" database, unless qualified by the query. Please post the error message on our forum or contact customer support with Query Id: 7a64950b-624d-4ea3-91d0-33be7a5e74b5

This corresponds to this Apache Hudi issue: (fixed in Hudi 0.11.0) and requires an AWS Athena change.

I'd be great to see an AWS fix for this issue to allow us to fully leverage Hudi on AWS.
