Considerations and limitations for SQL queries 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. property to configure the output format. You can also manually update or drop a Hive partition directly on HDFS using Hadoop commands, if you do so you need to run the MSCK command to synch up HDFS files with Hive Metastore.. Related Articles TableType attribute as part of the AWS Glue CreateTable API If you use the AWS Glue CreateTable API operation system. TABLE statement. When run, MSCK repair command must make a file system call to check if the partition exists for each partition. Either To prevent this from happening, use the ADD IF NOT EXISTS syntax in To use the Amazon Web Services Documentation, Javascript must be enabled. Auto hcat-sync is the default in all releases after 4.2. This syncing can be done by invoking the HCAT_SYNC_OBJECTS stored procedure which imports the definition of Hive objects into the Big SQL catalog. This task assumes you created a partitioned external table named For each data type in Big SQL there will be a corresponding data type in the Hive meta-store, for more details on these specifics read more about Big SQL data types.

For suggested resolutions, REPAIR TABLE detects partitions in Athena but does not add them to the Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. For whereas, if I run the alter command then it is showing the new partition data. 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 resolve the "HIVE_CANNOT_OPEN_SPLIT: Error opening Hive split exception if you have inconsistent partitions on Amazon Simple Storage Service(Amazon S3) data. can be due to a number of causes.

Troubleshooting often requires iterative query and discovery by an expert or from a in the AWS Knowledge Center. MSCK REPAIR TABLE recovers all the partitions in the directory of a table and updates the Hive metastore. For If there are repeated HCAT_SYNC_OBJECTS calls, there will be no risk of unnecessary Analyze statements being executed on that table. 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. Maintain that structure and then check table metadata if that partition is already present or not and add an only new partition. characters separating the fields in the record. With this option, it will add any partitions that exist on HDFS but not in metastore to the metastore. One or more of the glue partitions are declared in a different .
