> @zhangbutao hi, have you observed backward compatibility issues with Hive 2.3 client and Hive 4 HMS? also cc @sunchao @pan3793 I think it depends your use case, for this change, TrinoDB&StarRocks will use its customized thrift client and call `ThriftHiveMetastore$Client.recv_get_table_statistics_re` to fetch hive tables column stats, so it will occur compatibility issues. But as far as i know, Spark won't call this api to get hive tables column stats, so it is safe for Spark to integrate Hive4 using its embedded Hive2.3 client. BTW, we have used Spark3 to query hive4 tables for a long time, and we have not found any compatibility issues. -- This is an automated message from the Apache Git Service.
