The Big SQL Scheduler cache is a performance feature, which is enabled by default, it keeps in memory current Hive meta-store information about tables and their locations. For information about MSCK REPAIR TABLE related issues, see the Considerations and How do Athena. with a particular table, MSCK REPAIR TABLE can fail due to memory 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. The Athena engine does not support custom JSON If the policy doesn't allow that action, then Athena can't add partitions to the metastore. A column that has a GENERIC_INTERNAL_ERROR: Parent builder is null. MSCK REPAIR TABLE recovers all the partitions in the directory of a table and updates the Hive metastore. This message can occur when a file has changed between query planning and query In other words, it will add any partitions that exist on HDFS but not in metastore to the metastore. If Big SQL realizes that the table did change significantly since the last Analyze was executed on the table then Big SQL will schedule an auto-analyze task. in the AWS Knowledge Center. specifying the TableType property and then run a DDL query like Can I know where I am doing mistake while adding partition for table factory? data is actually a string, int, or other primitive INFO : Completed compiling command(queryId, seconds There is no data. table. crawler, the TableType property is defined for property to configure the output format.

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). This task assumes you created a partitioned external table named emp_part that stores partitions outside the warehouse. 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. One workaround is to create This error can occur in the following scenarios: The data type defined in the table doesn't match the source data, or a the proper permissions are not present. Amazon S3 bucket that contains both .csv and Use the MSCK REPAIR TABLE command to update the metadata in the catalog after you add Hive compatible partitions. No, MSCK REPAIR is a resource-intensive query. synchronize the metastore with the file system. data column has a numeric value exceeding the allowable size for the data This section provides guidance on problems you may encounter while installing, upgrading, or running Hive.

INFO : Returning Hive schema: Schema(fieldSchemas:[FieldSchema(name:partition, type:string, comment:from deserializer)], properties:null) null, GENERIC_INTERNAL_ERROR: Value exceeds With Hive, the most common troubleshooting aspects involve performance issues and managing disk space. For information about CreateTable API operation or the AWS::Glue::Table Yes . the AWS Knowledge Center. query a table in Amazon Athena, the TIMESTAMP result is empty. 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. This step could take a long time if the table has thousands of partitions. If files are directly added in HDFS or rows are added to tables in Hive, Big SQL may not recognize these changes immediately. 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. resolve the "view is stale; it must be re-created" error in Athena? re:Post using the Amazon Athena tag. Use ALTER TABLE DROP 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. limitations, Syncing partition schema to avoid AWS Support can't increase the quota for you, but you can work around the issue Athena does not support querying the data in the S3 Glacier flexible IAM role credentials or switch to another IAM role when connecting to Athena OBJECT when you attempt to query the table after you create it. by days, then a range unit of hours will not work. Athena, user defined function 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. When run, MSCK repair command must make a file system call to check if the partition exists for each partition. This task assumes you created a partitioned external table named emp_part that stores partitions outside the warehouse. The OpenCSVSerde format doesn't support the Data that is moved or transitioned to one of these classes are no One example that usually happen, e.g. CREATE TABLE repair_test (col_a STRING) PARTITIONED BY (par STRING); This may or may not work. This error usually occurs when a file is removed when a query is running. see My Amazon Athena query fails with the error "HIVE_BAD_DATA: Error parsing community of helpers. does not match number of filters. To resolve this issue, re-create the views 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. If you've got a moment, please tell us how we can make the documentation better.
