tags with the same name in different case. 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. The greater the number of new partitions, the more likely that a query will fail with a java.net.SocketTimeoutException: Read timed out error or an out of memory error message. If the HS2 service crashes frequently, confirm that the problem relates to HS2 heap exhaustion by inspecting the HS2 instance stdout log. MSCK REPAIR TABLE recovers all the partitions in the directory of a table and updates the Hive metastore. 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. The REPLACE option will drop and recreate the table in the Big SQL catalog and all statistics that were collected on that table would be lost.
