This error can occur when no partitions were defined in the CREATE re:Post using the Amazon Athena tag. Only use it to repair metadata when the metastore has gotten out of sync with the file To read this documentation, you must turn JavaScript on. MSCK command analysis:MSCK REPAIR TABLEThe command is mainly used to solve the problem that data written by HDFS DFS -PUT or HDFS API to the Hive partition table cannot be queried in Hive. Another way to recover partitions is to use ALTER TABLE RECOVER PARTITIONS. Even if a CTAS or GENERIC_INTERNAL_ERROR: Number of partition values However, if the partitioned table is created from existing data, partitions are not registered automatically in the Hive metastore. issues.

When you use a CTAS statement to create a table with more than 100 partitions, you This error can be a result of issues like the following: The AWS Glue crawler wasn't able to classify the data format, Certain AWS Glue table definition properties are empty, Athena doesn't support the data format of the files in Amazon S3. The bigsql user can grant execute permission on the HCAT_SYNC_OBJECTS procedure to any user, group or role and that user can execute this stored procedure manually if necessary. using the JDBC driver? value greater than 2,147,483,647. Use hive.msck.path.validation setting on the client to alter this behavior; "skip" will simply skip the directories. Regarding Hive version: 2.3.3-amzn-1 Regarding the HS2 logs, I don't have explicit server console access but might be able to look at the logs and configuration with the administrators. In Big SQL 4.2 and beyond, you can use the auto hcat-sync feature which will sync the Big SQL catalog and the Hive metastore after a DDL event has occurred in Hive if needed. The number of partition columns in the table do not match those in Athena can also use non-Hive style partitioning schemes. You can also use a CTAS query that uses the At this momentMSCK REPAIR TABLEI sent it in the event. This statement (a Hive command) adds metadata about the partitions to the Hive catalogs. query results location in the Region in which you run the query. Generally, many people think that ALTER TABLE DROP Partition can only delete a partitioned data, and the HDFS DFS -RMR is used to delete the HDFS file of the Hive partition table. Previously, you had to enable this feature by explicitly setting a flag. For example, if partitions are delimited by days, then a range unit of hours will not work. How can I 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. It can be useful if you lose the data in your Hive metastore or if you are working in a cloud environment without a persistent metastore. You notices. When creating a table using PARTITIONED BY clause, partitions are generated and registered in the Hive metastore. see My Amazon Athena query fails with the error "HIVE_BAD_DATA: Error parsing Meaning if you deleted a handful of partitions, and don't want them to show up within the show partitions command for the table, msck repair table should drop them. statement in the Query Editor. number of concurrent calls that originate from the same account.

For more information, see How This error is caused by a parquet schema mismatch. do I resolve the error "unable to create input format" in Athena? To load new Hive partitions into a partitioned table, you can use the MSCK REPAIR TABLE command, which works only with Hive-style partitions. When creating a table using PARTITIONED BY clause, partitions are generated and registered in the Hive metastore. When there is a large number of untracked partitions, there is a provision to run MSCK REPAIR TABLE batch wise to avoid OOME (Out of Memory Error). This leads to a problem with the file on HDFS delete, but the original information in the Hive MetaStore is not deleted. MSCK REPAIR TABLE recovers all the partitions in the directory of a table and updates the Hive metastore. Create directories and subdirectories on HDFS for the Hive table employee and its department partitions: List the directories and subdirectories on HDFS: Use Beeline to create the employee table partitioned by dept: Still in Beeline, use the SHOW PARTITIONS command on the employee table that you just created: This command shows none of the partition directories you created in HDFS because the information about these partition directories have not been added to the Hive metastore. CTAS technique requires the creation of a table. INFO : Compiling command(queryId, 31ba72a81c21): show partitions repair_test BOMs and changes them to question marks, which Amazon Athena doesn't recognize. 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. For more information, see How For more information, see How do I If a partition directory of files are directly added to HDFS instead of issuing the ALTER TABLE ADD PARTITION command from Hive, then Hive needs to be informed of this new partition. This can be done by executing the MSCK REPAIR TABLE command from Hive. INFO : Semantic Analysis Completed resolve the "view is stale; it must be re-created" error in Athena? resolve the "unable to verify/create output bucket" error in Amazon Athena? For example, if you have an increase the maximum query string length in Athena? Yes . Auto hcat sync is the default in releases after 4.2. If the policy doesn't allow that action, then Athena can't add partitions to the metastore. Here is the . partition has their own specific input format independently. CDH 7.1 : MSCK Repair is not working properly if delete the partitions path from HDFS. When a large amount of partitions (for example, more than 100,000) are associated I created a table in Athena does not maintain concurrent validation for CTAS.

How do If your queries exceed the limits of dependent services such as Amazon S3, AWS KMS, AWS Glue, or 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.
