Naveen Gangam created HIVE-24448: ------------------------------------ Summary: Support case-sensitivity for tables in REMOTE database. Key: HIVE-24448 URL: https://issues.apache.org/jira/browse/HIVE-24448 Project: Hive Issue Type: Sub-task Components: HiveServer2 Affects Versions: 4.0.0 Reporter: Naveen Gangam
Hive tables are case-insensitive. So any case specified in user queries are converted to lower case for query planning and all of the HMS metadata is also persisted as lower case names. However, with REMOTE data sources, certain data source will support case-sensitivity for tables. So HiveServer2 query planner needs to preserve user-provided case to be used with HMS APIs, for HMS to be able to fetch the metadata from a remote data source. We now see something like this {noformat} 2020-11-25T16:45:36,402 WARN [HiveServer2-Handler-Pool: Thread-76] thrift.ThriftCLIService: Error executing statement:
