Athena treats sources files that start with an underscore (_) or a dot (.) AWS Support can't increase the quota for you, but you can work around the issue partitions are defined in AWS Glue. For example, if you have an -- create a partitioned table from existing data /tmp/namesAndAges.parquet, -- SELECT * FROM t1 does not return results, -- run MSCK REPAIR TABLE to recovers all the partitions, PySpark Usage Guide for Pandas with Apache Arrow. MSCK REPAIR TABLE recovers all the partitions in the directory of a table and updates the Hive metastore. type. resolve the error "GENERIC_INTERNAL_ERROR" when I query a table in its a strange one. 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. EXTERNAL_TABLE or VIRTUAL_VIEW. ok. just tried that setting and got a slightly different stack trace but end result still was the NPE. INFO : Compiling command(queryId, from repair_test 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. There is no data.Repair needs to be repaired. limitations, Syncing partition schema to avoid MAX_INT You might see this exception when the source 07-26-2021 template. type BYTE.

Thanks for letting us know we're doing a good job! This issue can occur if an Amazon S3 path is in camel case instead of lower case or an are ignored. Hive shell are not compatible with Athena. IAM role credentials or switch to another IAM role when connecting to Athena Either endpoint like us-east-1.amazonaws.com. How can I More interesting happened behind. remove one of the partition directories on the file system. For Center. query a table in Amazon Athena, the TIMESTAMP result is empty. in the AWS There are two ways if the user still would like to use those reserved keywords as identifiers: (1) use quoted identifiers, (2) set hive.support.sql11.reserved.keywords =false. 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. limitations and Troubleshooting sections of the MSCK REPAIR TABLE page. each JSON document to be on a single line of text with no line termination Azure Databricks uses multiple threads for a single MSCK REPAIR by default, which splits createPartitions () into batches. INFO : Starting task [Stage, b6e1cdbe1e25): show partitions repair_test define a column as a map or struct, but the underlying Hive stores a list of partitions for each table in its metastore. Athena does not maintain concurrent validation for CTAS. For more information, see the "Troubleshooting" section of the MSCK REPAIR TABLE topic. This error is caused by a parquet schema mismatch. The bucket also has a bucket policy like the following that forces IAM role credentials or switch to another IAM role when connecting to Athena Search results are not available at this time. (UDF). The Athena engine does not support custom JSON But because our Hive version is 1.1.0-CDH5.11.0, this method cannot be used.
