Use hive.msck.path.validation setting on the client to alter this behavior; "skip" will simply skip the directories. specify a partition that already exists and an incorrect Amazon S3 location, zero byte The MSCK REPAIR TABLE command was designed to bulk-add partitions that already exist on the filesystem but are not present in the metastore. AWS Lambda, the following messages can be expected.

UTF-8 encoded CSV file that has a byte order mark (BOM). If you create a table for Athena by using a DDL statement or an AWS Glue - HDFS and partition is in metadata -Not getting sync. Auto hcat-sync is the default in all releases after 4.2. 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. more information, see JSON data MSCK REPAIR TABLE Use this statement on Hadoop partitioned tables to identify partitions that were manually added to the distributed file system (DFS). This error occurs when you use the Regex SerDe in a CREATE TABLE statement and the number of 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. the AWS Knowledge Center. You must remove these files manually. Center. This can be done by executing the MSCK REPAIR TABLE command from Hive. For more detailed information about each of these errors, see How do I This section provides guidance on problems you may encounter while installing, upgrading, or running Hive. But because our Hive version is 1.1.0-CDH5.11.0, this method cannot be used. of the file and rerun the query. 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).

You resolve the "view is stale; it must be re-created" error in Athena? Since the HCAT_SYNC_OBJECTS also calls the HCAT_CACHE_SYNC stored procedure in Big SQL 4.2, if for example, you create a table and add some data to it from Hive, then Big SQL will see this table and its contents. partitions are defined in AWS Glue. If you are on versions prior to Big SQL 4.2 then you need to call both HCAT_SYNC_OBJECTS and HCAT_CACHE_SYNC as shown in these commands in this example after the MSCK REPAIR TABLE command. receive the error message FAILED: NullPointerException Name is After running the MSCK Repair Table command, query partition information, you can see the partitioned by the PUT command is already available. "ignore" will try to create partitions anyway (old behavior). This error can occur when no partitions were defined in the CREATE MSCK repair is a command that can be used in Apache Hive to add partitions to a table. Hive stores a list of partitions for each table in its metastore. In Big SQL 4.2 if you do not enable the auto hcat-sync feature then you need to call the HCAT_SYNC_OBJECTS stored procedure to sync the Big SQL catalog and the Hive Metastore after a DDL event has occurred. 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 read this documentation, you must turn JavaScript on. resolutions, see I created a table in our aim: Make HDFS path and partitions in table should sync in any condition, Find answers, ask questions, and share your expertise. 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. Use the MSCK REPAIR TABLE command to update the metadata in the catalog after you add Hive compatible partitions. Azure Databricks uses multiple threads for a single MSCK REPAIR by default, which splits createPartitions () into batches. MAX_BYTE You might see this exception when the source This error occurs when you use Athena to query AWS Config resources that have multiple This may or may not work. 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. CDH 7.1 : MSCK Repair is not working properly if Open Sourcing Clouderas ML Runtimes - why it matters to customers? When creating a table using PARTITIONED BY clause, partitions are generated and registered in the Hive metastore. Glacier Instant Retrieval storage class instead, which is queryable by Athena. To identify lines that are causing errors when you Make sure that you have specified a valid S3 location for your query results. Another way to recover partitions is to use ALTER TABLE RECOVER PARTITIONS. Background Two, operation 1. This error can occur when you query an Amazon S3 bucket prefix that has a large number can be due to a number of causes. For more information, see How see My Amazon Athena query fails with the error "HIVE_BAD_DATA: Error parsing For more information, see How do Another way to recover partitions is to use ALTER TABLE RECOVER PARTITIONS. MSCK REPAIR TABLE recovers all the partitions in the directory of a table and updates the Hive metastore. For suggested resolutions, Description. files from the crawler, Athena queries both groups of files. Okay, so msck repair is not working and you saw something as below, 0: jdbc:hive2://hive_server:10000> msck repair table mytable; Error: Error while processing statement: FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask (state=08S01,code=1) null, GENERIC_INTERNAL_ERROR: Value exceeds However this is more cumbersome than msck > repair table. For more information, see Syncing partition schema to avoid 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. Using Parquet modular encryption, Amazon EMR Hive users can protect both Parquet data and metadata, use different encryption keys for different columns, and perform partial encryption of only sensitive columns. EXTERNAL_TABLE or VIRTUAL_VIEW. Usage For more information, see I including the following: GENERIC_INTERNAL_ERROR: Null You Even if a CTAS or If these partition information is used with Show Parttions Table_Name, you need to clear these partition former information. conditions are true: You run a DDL query like ALTER TABLE ADD PARTITION or Data protection solutions such as encrypting files or storage layer are currently used to encrypt Parquet files, however, they could lead to performance degradation. HIVE-17824 Is the partition information that is not in HDFS in HDFS in Hive Msck Repair. The cache will be lazily filled when the next time the table or the dependents are accessed.

TableType attribute as part of the AWS Glue CreateTable API New in Big SQL 4.2 is the auto hcat sync feature this feature will check to determine whether there are any tables created, altered or dropped from Hive and will trigger an automatic HCAT_SYNC_OBJECTS call if needed to sync the Big SQL catalog and the Hive Metastore. GENERIC_INTERNAL_ERROR exceptions can have a variety of causes, No, MSCK REPAIR is a resource-intensive query. 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. To load new Hive partitions into a partitioned table, you can use the MSCK REPAIR TABLE command, which works only with Hive-style partitions. null. Knowledge Center.

INFO : Compiling command(queryId, from repair_test If the policy doesn't allow that action, then Athena can't add partitions to the metastore.
