Known issues identified in the March 31, 2026 release

CDPD-97613: Materialized view rebuild fails for Iceberg tables: Materialized view rebuild fails when the base table is an Iceberg table and the materialized view is implicitly created as an ACID table due to metastore.create.as.acid=true resulting in an error. During rebuild, no transaction is started but an entry is created in the MATERIALIZATION_REBUILD_LOCKS table and not cleared, causing subsequent attempts to fail due to an existing lock entry.; Set the metastore.create.as.acid property value to false.
This issue also occurs when the materialized view is an Iceberg table and is tracked in upstream as part of HIVE-29436
