To directly answer your question msck repair table, will check if partitions for a table is active. What is MSCK repair in Hive? can I troubleshoot the error "FAILED: SemanticException table is not partitioned Statistics can be managed on internal and external tables and partitions for query optimization. For more information, see I Note that Big SQL will only ever schedule 1 auto-analyze task against a table after a successful HCAT_SYNC_OBJECTS call. If, however, new partitions are directly added to HDFS (say by using hadoop fs -put command) or removed from HDFS, the metastore (and hence Hive) will not be aware of these changes to partition information unless the user runs ALTER TABLE table_name ADD/DROP PARTITION commands on each of the newly added or removed partitions, respectively. The Hive metastore stores the metadata for Hive tables, this metadata includes table definitions, location, storage format, encoding of input files, which files are associated with which table, how many files there are, types of files, column names, data types etc. GitHub. specifying the TableType property and then run a DDL query like its a strange one. The bucket also has a bucket policy like the following that forces For more information, see How TINYINT is an 8-bit signed integer in You have a bucket that has default Big SQL uses these low level APIs of Hive to physically read/write data. Athena does not support querying the data in the S3 Glacier flexible (version 2.1.0 and earlier) Create/Drop/Alter/Use Database Create Database limitations and Troubleshooting sections of the MSCK REPAIR TABLE page. The cache will be lazily filled when the next time the table or the dependents are accessed. If you use the AWS Glue CreateTable API operation Problem: There is data in the previous hive, which is broken, causing the Hive metadata information to be lost, but the data on the HDFS on the HDFS is not lost, and the Hive partition is not shown after returning the form.
Error when running MSCK REPAIR TABLE in parallel - Azure Databricks The greater the number of new partitions, the more likely that a query will fail with a java.net.SocketTimeoutException: Read timed out error or an out of memory error message.

"ignore" will try to create partitions anyway (old behavior). MSCK REPAIR TABLE recovers all the partitions in the directory of a table and updates the Hive metastore. more information, see JSON data 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). files in the OpenX SerDe documentation on GitHub. increase the maximum query string length in Athena? in Athena. Repair partitions manually using MSCK repair The MSCK REPAIR TABLE command was designed to manually add partitions that are added to or removed from the file system, but are not present in the Hive metastore.
