Temporary credentials have a maximum lifespan of 12 hours. If you are on versions prior to Big SQL 4.2 then you need to call both HCAT_SYNC_OBJECTS and HCAT_CACHE_SYNC as shown in these commands in this example after the MSCK REPAIR TABLE command. This will sync the Big SQL catalog and the Hive Metastore and also automatically call the HCAT_CACHE_SYNC stored procedure on that table to flush table metadata information from the Big SQL Scheduler cache. MSCK REPAIR TABLE recovers all the partitions in the directory of a table and updates the Hive metastore.

INFO : Starting task [Stage, b6e1cdbe1e25): show partitions repair_test To load new Hive partitions into a partitioned table, you can use the MSCK REPAIR TABLE command, which works only with Hive-style partitions. I've just implemented the manual alter table / add partition steps. (UDF). The following examples shows how this stored procedure can be invoked: Performance tip where possible invoke this stored procedure at the table level rather than at the schema level. list of functions that Athena supports, see Functions in Amazon Athena or run the SHOW FUNCTIONS .json files and you exclude the .json manually.

Use the MSCK REPAIR TABLE command to update the metadata in the catalog after you add Hive compatible partitions. primitive type (for example, string) in AWS Glue. For more information, see When I 2.Run metastore check with repair table option. synchronize the metastore with the file system. In this case, the MSCK REPAIR TABLE command is useful to resynchronize Hive metastore metadata with the file system. The MSCK REPAIR TABLE command scans a file system such as Amazon S3 for Hive compatible partitions that were added to the file system after the table was created. resolve this issue, drop the table and create a table with new partitions.

If files corresponding to a Big SQL table are directly added or modified in HDFS or data is inserted into a table from Hive, and you need to access this data immediately, then you can force the cache to be flushed by using the HCAT_CACHE_SYNC stored procedure. In addition, problems can also occur if the metastore metadata gets out of To directly answer your question msck repair table, will check if partitions for a table is active.
