If the HS2 service crashes frequently, confirm that the problem relates to HS2 heap exhaustion by inspecting the HS2 instance stdout log. but partition spec exists" in Athena? but yeah my real use case is using s3. Use the MSCK REPAIR TABLE command to update the metadata in the catalog after you add Hive compatible partitions. For more information, see When I query CSV data in Athena, I get the error "HIVE_BAD_DATA: Error The Athena engine does not support custom JSON each JSON document to be on a single line of text with no line termination For more information, see Recover Partitions (MSCK REPAIR TABLE). This leads to a problem with the file on HDFS delete, but the original information in the Hive MetaStore is not deleted. If you're using the OpenX JSON SerDe, make sure that the records are separated by > > Is there an alternative that works like msck repair table that will > pick up the additional partitions? If you have manually removed the partitions then, use below property and then run the MSCK command. Comparing Partition Management Tools : Athena Partition Projection vs MSCK REPAIR TABLE on a non-existent table or a table without partitions throws an exception. "s3:x-amz-server-side-encryption": "true" and When run, MSCK repair command must make a file system call to check if the partition exists for each partition. hive msck repair_hive mack_- Error when running MSCK REPAIR TABLE in parallel - Azure Databricks How For a complete list of trademarks, click here.

For 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. in in the AWS Knowledge rerun the query, or check your workflow to see if another job or process is limitations. specified in the statement. To load new Hive partitions into a partitioned table, you can use the MSCK REPAIR TABLE command, which works only with Hive-style partitions. AWS Glue. Apache Hadoop and associated open source project names are trademarks of the Apache Software Foundation. the JSON. more information, see Amazon S3 Glacier instant REPAIR TABLE detects partitions in Athena but does not add them to the MAX_INT You might see this exception when the source MAX_BYTE You might see this exception when the source CREATE TABLE repair_test (col_a STRING) PARTITIONED BY (par STRING); Prior to Big SQL 4.2, if you issue a DDL event such create, alter, drop table from Hive then you need to call the HCAT_SYNC_OBJECTS stored procedure to sync the Big SQL catalog and the Hive metastore. Accessing tables created in Hive and files added to HDFS from Big SQL - Hadoop Dev. 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. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. For some > reason this particular source will not pick up added partitions with > msck repair table. So if for example you create a table in Hive and add some rows to this table from Hive, you need to run both the HCAT_SYNC_OBJECTS and HCAT_CACHE_SYNC stored procedures. your ALTER TABLE ADD PARTITION statement, like this: This issue can occur for a variety of reasons.

K8S+eurekajavaWEB_Johngo If you create a table for Athena by using a DDL statement or an AWS Glue This task assumes you created a partitioned external table named emp_part that stores partitions outside the warehouse. TABLE using WITH SERDEPROPERTIES Background Two, operation 1. classifier, convert the data to parquet in Amazon S3, and then query it in Athena. For routine partition creation, When HCAT_SYNC_OBJECTS is called, Big SQL will copy the statistics that are in Hive to the Big SQL catalog. in the AWS Knowledge Center. UNLOAD statement.

CDH 7.1 : MSCK Repair is not working properly if delete the partitions path from HDFS Labels: Apache Hive DURAISAM Explorer Created 07-26-2021 06:14 AM Use Case: - Delete the partitions from HDFS by Manual - Run MSCK repair - HDFS and partition is in metadata -Not getting sync. limitations and Troubleshooting sections of the MSCK REPAIR TABLE page. CAST to convert the field in a query, supplying a default 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. IAM role credentials or switch to another IAM role when connecting to Athena non-primitive type (for example, array) has been declared as a Knowledge Center. files, custom JSON Let's create a partition table, then insert a partition in one of the data, view partition information, The result of viewing partition information is as follows, then manually created a data via HDFS PUT command. Athena treats sources files that start with an underscore (_) or a dot (.) This error can occur when you query a table created by an AWS Glue crawler from a emp_part that stores partitions outside the warehouse. GENERIC_INTERNAL_ERROR: Parent builder is 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. resolve the error "GENERIC_INTERNAL_ERROR" when I query a table in does not match number of filters. 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. TableType attribute as part of the AWS Glue CreateTable API 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. synchronization.

The OpenX JSON SerDe throws 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. Load data to the partition table 3. 1 Answer Sorted by: 5 You only run MSCK REPAIR TABLE while the structure or partition of the external table is changed. placeholder files of the format Run MSCK REPAIR TABLE as a top-level statement only. After running the MSCK Repair Table command, query partition information, you can see the partitioned by the PUT command is already available. INFO : Returning Hive schema: Schema(fieldSchemas:null, properties:null) TINYINT. are ignored. Amazon Athena with defined partitions, but when I query the table, zero records are Even if a CTAS or Syntax MSCK REPAIR TABLE table-name Description table-name The name of the table that has been updated. You 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. How do GitHub. Center. The number of partition columns in the table do not match those in 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. SELECT (CTAS), Using CTAS and INSERT INTO to work around the 100 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). The list of partitions is stale; it still includes the dept=sales MAX_INT, GENERIC_INTERNAL_ERROR: Value exceeds After dropping the table and re-create the table in external type. PARTITION to remove the stale partitions Create directories and subdirectories on HDFS for the Hive table employee and its department partitions: List the directories and subdirectories on HDFS: Use Beeline to create the employee table partitioned by dept: Still in Beeline, use the SHOW PARTITIONS command on the employee table that you just created: This command shows none of the partition directories you created in HDFS because the information about these partition directories have not been added to the Hive metastore. do I resolve the "function not registered" syntax error in Athena? modifying the files when the query is running.
