For more information, see I Syntax MSCK REPAIR TABLE table-name Description table-name The name of the table that has been updated. same Region as the Region in which you run your query. So if for example you create a table in Hive and add some rows to this table from Hive, you need to run both the HCAT_SYNC_OBJECTS and HCAT_CACHE_SYNC stored procedures. For more information, see How can I as Prior to Big SQL 4.2, if you issue a DDL event such create, alter, drop table from Hive then you need to call the HCAT_SYNC_OBJECTS stored procedure to sync the Big SQL catalog and the Hive metastore. But because our Hive version is 1.1.0-CDH5.11.0, this method cannot be used. When a table is created, altered or dropped in Hive, the Big SQL Catalog and the Hive Metastore need to be synchronized so that Big SQL is aware of the new or modified table. To resolve these issues, reduce the The REPLACE option will drop and recreate the table in the Big SQL catalog and all statistics that were collected on that table would be lost. IAM role credentials or switch to another IAM role when connecting to Athena There are two ways if the user still would like to use those reserved keywords as identifiers: (1) use quoted identifiers, (2) set hive.support.sql11.reserved.keywords =false. For more information, see Syncing partition schema to avoid When the table is repaired in this way, then Hive will be able to see the files in this new directory and if the auto hcat-sync feature is enabled in Big SQL 4.2 then Big SQL will be able to see this data as well. When creating a table using PARTITIONED BY clause, partitions are generated and registered in the Hive metastore. location.

The default option for MSC command is ADD PARTITIONS. This error can occur if the specified query result location doesn't exist or if retrieval or S3 Glacier Deep Archive storage classes. In this case, the MSCK REPAIR TABLE command is useful to resynchronize Hive metastore metadata with the file system. retrieval, Specifying a query result However, if the partitioned table is created from existing data, partitions are not registered automatically in the Hive metastore. the AWS Knowledge Center. Using Parquet modular encryption, Amazon EMR Hive users can protect both Parquet data and metadata, use different encryption keys for different columns, and perform partial encryption of only sensitive columns. Attached to the official website Recover Partitions (MSCK REPAIR TABLE). re:Post using the Amazon Athena tag. Method 2: Run the set hive.msck.path.validation=skip command to skip invalid directories. See Tuning Apache Hive Performance on the Amazon S3 Filesystem in CDH or Configuring ADLS Gen1 can I troubleshoot the error "FAILED: SemanticException table is not partitioned In Big SQL 4.2, if the auto hcat-sync feature is not enabled (which is the default behavior) then you will need to call the HCAT_SYNC_OBJECTS stored procedure.
