MAX_INT You might see this exception when the source GENERIC_INTERNAL_ERROR: Number of partition values Tried multiple times and Not getting sync after upgrading CDH 6.x to CDH 7.x, Created The Scheduler cache is flushed every 20 minutes. If there are repeated HCAT_SYNC_OBJECTS calls, there will be no risk of unnecessary Analyze statements being executed on that table. For information about MSCK REPAIR TABLE related issues, see the Considerations and Azure Databricks uses multiple threads for a single MSCK REPAIR by default, which splits createPartitions() into batches. However this is more cumbersome than msck > repair table. If partitions are manually added to the distributed file system (DFS), the metastore is not aware of these partitions. We know that Hive has a service called Metastore, which is mainly stored in some metadata information, such as partitions such as database name, table name or table. Amazon Athena. limitations, Syncing partition schema to avoid You must remove these files manually. issue, check the data schema in the files and compare it with schema declared in limitations and Troubleshooting sections of the MSCK REPAIR TABLE page. A good use of MSCK REPAIR TABLE is to repair metastore metadata after you move your data files to cloud storage, such as Amazon S3. msck repair table tablenamehivelocationHivehive . to or removed from the file system, but are not present in the Hive metastore. more information, see Amazon S3 Glacier instant With this option, it will add any partitions that exist on HDFS but not in metastore to the metastore. remove one of the partition directories on the file system. example, if you are working with arrays, you can use the UNNEST option to flatten in the Hive users run Metastore check command with the repair table option (MSCK REPAIR table) to update the partition metadata in the Hive metastore for partitions that were directly added to or removed from the file system (S3 or HDFS). > > Is there an alternative that works like msck repair table that will > pick up the additional partitions? 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. 2016-07-15T03:13:08,102 DEBUG [main]: parse.ParseDriver (: ()) - Parse Completed To read this documentation, you must turn JavaScript on.

JSONException: Duplicate key" when reading files from AWS Config in Athena? Thanks for letting us know we're doing a good job! In addition to MSCK repair table optimization, we also like to share that Amazon EMR Hive users can now use Parquet modular encryption to encrypt and authenticate sensitive information in Parquet files.
