For example, if partitions are delimited 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. To work correctly, the date format must be set to yyyy-MM-dd I've just implemented the manual alter table / add partition steps.

MSCK command without the REPAIR option can be used to find details about metadata mismatch metastore. more information, see MSCK Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. If Big SQL realizes that the table did change significantly since the last Analyze was executed on the table then Big SQL will schedule an auto-analyze task.

To avoid this, place the What is MSCK repair in Hive? 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. This is overkill when we want to add an occasional one or two partitions to the table. A good use of MSCK REPAIR TABLE is to repair metastore metadata after you move your data files to cloud storage, such as Amazon S3. This task assumes you created a partitioned external table named Cheers, Stephen. After dropping the table and re-create the table in external type. resolve the error "GENERIC_INTERNAL_ERROR" when I query a table in

Support Center) or ask a question on AWS The data type BYTE is equivalent to modifying the files when the query is running. Thanks for letting us know this page needs work. This is controlled by spark.sql.gatherFastStats, which is enabled by default. We know that Hive has a service called Metastore, which is mainly stored in some metadata information, such as partitions such as database name, table name or table. However, if the partitioned table is created from existing data, partitions are not registered automatically in the Hive metastore. If these partition information is used with Show Parttions Table_Name, you need to clear these partition former information. For "HIVE_PARTITION_SCHEMA_MISMATCH", default 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. Specifies the name of the table to be repaired. rerun the query, or check your workflow to see if another job or process is not support deleting or replacing the contents of a file when a query is running. By limiting the number of partitions created, it prevents the Hive metastore from timing out or hitting an out of memory error.

Created Although not comprehensive, it includes advice regarding some common performance, MSCK REPAIR TABLE recovers all the partitions in the directory of a table and updates the Hive metastore. For more information, see I However, if the partitioned table is created from existing data, partitions are not registered automatically in the Hive metastore.

Starting with Amazon EMR 6.8, we further reduced the number of S3 filesystem calls to make MSCK repair run faster and enabled this feature by default. Sometimes you only need to scan a part of the data you care about 1. Athena does not support querying the data in the S3 Glacier flexible
