AWS Knowledge Center. This error can occur when you try to query logs written For Amazon Athena with defined partitions, but when I query the table, zero records are For hive> Msck repair table <db_name>.<table_name> which will add metadata about partitions to the Hive metastore for partitions for which such metadata doesn't already exist. see Using CTAS and INSERT INTO to work around the 100 Considerations and limitations for SQL queries custom classifier. As long as the table is defined in the Hive MetaStore and accessible in the Hadoop cluster then both BigSQL and Hive can access it.
