> Tajo stores a list of partitions for each table in its CatalogStore. If, however, new partitions are directly added to HDFS, the CatalogStore will not be aware of these partitions unless the user runs ALTER TABLE table_name ADD PARTITION commands on each of the newly added partitions.
> However, users can run a CatalogStore check command with the repair table option:
> {code:xml}
> MSCK REPAIR TABLE <table_name>
> {code}
> For the reference, I've referenced hive msck command.
