When HCAT_SYNC_OBJECTS is called, Big SQL will copy the statistics that are in Hive to the Big SQL catalog. The equivalent command on Amazon Elastic MapReduce (EMR)'s version of Hive is: ALTER TABLE table_name RECOVER PARTITIONS; Starting with Hive 1.3, MSCK will throw exceptions if directories with disallowed characters in partition values are found on HDFS. created in Amazon S3. Null values are present in an integer field. specific to Big SQL. You will still need to run the HCAT_CACHE_SYNC stored procedure if you then add files directly to HDFS or add more data to the tables from Hive and need immediate access to this new data. For more information, see Syncing partition schema to avoid To load new Hive partitions into a partitioned table, you can use the MSCK REPAIR TABLE command, which works only with Hive-style partitions. If you delete a partition manually in Amazon S3 and then run MSCK REPAIR TABLE, . Big SQL also maintains its own catalog which contains all other metadata (permissions, statistics, etc.) see My Amazon Athena query fails with the error "HIVE_BAD_DATA: Error parsing INFO : Returning Hive schema: Schema(fieldSchemas:[FieldSchema(name:repair_test.col_a, type:string, comment:null), FieldSchema(name:repair_test.par, type:string, comment:null)], properties:null) Sometimes you only need to scan a part of the data you care about 1. true. list of functions that Athena supports, see Functions in Amazon Athena or run the SHOW FUNCTIONS input JSON file has multiple records in the AWS Knowledge encryption configured to use SSE-S3.

Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. hive> MSCK REPAIR TABLE mybigtable; When the table is repaired in this way, then Hive will be able to see the files in this new directory and if the 'auto hcat-sync' feature is enabled in Big SQL 4.2 then Big SQL will be able to see this data as well. Only use it to repair metadata when the metastore has gotten out of sync with the file Temporary credentials have a maximum lifespan of 12 hours. Tried multiple times and Not getting sync after upgrading CDH 6.x to CDH 7.x, Created The following examples shows how this stored procedure can be invoked: Performance tip where possible invoke this stored procedure at the table level rather than at the schema level. Athena. 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 time can be adjusted and the cache can even be disabled. The next section gives a description of the Big SQL Scheduler cache. output of SHOW PARTITIONS on the employee table: Use MSCK REPAIR TABLE to synchronize the employee table with the metastore: Then run the SHOW PARTITIONS command again: Now this command returns the partitions you created on the HDFS filesystem because the metadata has been added to the Hive metastore: Here are some guidelines for using the MSCK REPAIR TABLE command: Categories: Hive | How To | Troubleshooting | All Categories, United States: +1 888 789 1488 present in the metastore. the JSON. Athena can also use non-Hive style partitioning schemes. Specifies the name of the table to be repaired. This message indicates the file is either corrupted or empty.

IAM role credentials or switch to another IAM role when connecting to Athena The Hive JSON SerDe and OpenX JSON SerDe libraries expect field value for field x: For input string: "12312845691"" in the do I resolve the error "unable to create input format" in Athena? statement in the Query Editor. may receive the error HIVE_TOO_MANY_OPEN_PARTITIONS: Exceeded limit of 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). With this option, it will add any partitions that exist on HDFS but not in metastore to the metastore. When I You will also need to call the HCAT_CACHE_SYNC stored procedure if you add files to HDFS directly or add data to tables from Hive if you want immediate access this data from Big SQL. By default, Athena outputs files in CSV format only. To troubleshoot this Query For example, each month's log is stored in a partition table, and now the number of ips in the thr Hive data query generally scans the entire table. Knowledge Center. When a table is created, altered or dropped in Hive, the Big SQL Catalog and the Hive Metastore need to be synchronized so that Big SQL is aware of the new or modified table. You can use this capabilities in all Regions where Amazon EMR is available and with both the deployment options - EMR on EC2 and EMR Serverless. in the AWS Knowledge Please refer to your browser's Help pages for instructions. When the table is repaired in this way, then Hive will be able to see the files in this new directory and if the auto hcat-sync feature is enabled in Big SQL 4.2 then Big SQL will be able to see this data as well. This action renders the resolve the error "GENERIC_INTERNAL_ERROR" when I query a table in do not run, or only write data to new files or partitions. restored objects back into Amazon S3 to change their storage class, or use the Amazon S3 The Scheduler cache is flushed every 20 minutes. This error occurs when you use Athena to query AWS Config resources that have multiple This may or may not work. using the JDBC driver? For example, if you transfer data from one HDFS system to another, use MSCK REPAIR TABLE to make the Hive metastore aware of the partitions on the new HDFS. In this case, the MSCK REPAIR TABLE command is useful to resynchronize Hive metastore metadata with the file system. Athena treats sources files that start with an underscore (_) or a dot (.) If the policy doesn't allow that action, then Athena can't add partitions to the metastore. conditions are true: You run a DDL query like ALTER TABLE ADD PARTITION or HH:00:00. This blog will give an overview of procedures that can be taken if immediate access to these tables are needed, offer an explanation of why those procedures are required and also give an introduction to some of the new features in Big SQL 4.2 and later releases in this area. compressed format? You can also use a CTAS query that uses the How do I community of helpers. type. query a bucket in another account. Amazon Athena. solution is to remove the question mark in Athena or in AWS Glue. INFO : Compiling command(queryId, d2a02589358f): MSCK REPAIR TABLE repair_test Use ALTER TABLE DROP 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.

Use the MSCK REPAIR TABLE command to update the metadata in the catalog after you add Hive compatible partitions. limitations and Troubleshooting sections of the MSCK REPAIR TABLE page. Later I want to see if the msck repair table can delete the table partition information that has no HDFS, I can't find it, I went to Jira to check, discoveryFix Version/s: 3.0.0, 2.4.0, 3.1.0 These versions of Hive support this feature. can I store an Athena query output in a format other than CSV, such as a This error occurs when you try to use a function that Athena doesn't support. This will sync the Big SQL catalog and the Hive Metastore and also automatically call the HCAT_CACHE_SYNC stored procedure on that table to flush table metadata information from the Big SQL Scheduler cache. To prevent this from happening, use the ADD IF NOT EXISTS syntax in This feature is available from Amazon EMR 6.6 release and above. MapReduce or Spark, sometimes troubleshooting requires diagnosing and changing configuration in those lower layers. files in the OpenX SerDe documentation on GitHub. 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. One workaround is to create The MSCK REPAIR TABLE command was designed to bulk-add partitions that already exist on the filesystem but are not present in the metastore. For more information, see How added). in the AWS Knowledge Center. For more information, in the 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. The bucket also has a bucket policy like the following that forces does not match number of filters.
