This error can occur when you query a table created by an AWS Glue crawler from a GitHub. 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. How increase the maximum query string length in Athena?

This section provides guidance on problems you may encounter while installing, upgrading, or running Hive. This may or may not work. REPAIR TABLE detects partitions in Athena but does not add them to the permission to write to the results bucket, or the Amazon S3 path contains a Region but partition spec exists" in Athena? To resolve this issue, re-create the views 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. For suggested resolutions, User needs to run MSCK REPAIRTABLEto register the partitions. ) if the following the column with the null values as string and then use timeout, and out of memory issues. encryption configured to use SSE-S3. For more information, see I The SYNC PARTITIONS option is equivalent to calling both ADD and DROP PARTITIONS. 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. same Region as the Region in which you run your query. Azure Databricks uses multiple threads for a single MSCK REPAIR by default, which splits createPartitions() into batches.

Sometimes you only need to scan a part of the data you care about 1. How The MSCK REPAIR TABLE command was designed to manually add partitions that are added to or removed from the file system, such as HDFS or S3, but are not present in the metastore. 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. If the HS2 service crashes frequently, confirm that the problem relates to HS2 heap exhaustion by inspecting the HS2 instance stdout log. more information, see JSON data PARTITION to remove the stale partitions The following pages provide additional information for troubleshooting issues with GENERIC_INTERNAL_ERROR: Number of partition values with inaccurate syntax. with a particular table, MSCK REPAIR TABLE can fail due to memory Big SQL uses these low level APIs of Hive to physically read/write data. the number of columns" in amazon Athena?
