Summary: Implement CatalogStore::updateTable
Key: TAJO-1213
URL: https://issues.apache.org/jira/browse/TAJO-1213
Project: Tajo
Issue Type: Improvement
Components: catalog
Reporter: Jaehwa Jung
Assignee: Jaehwa Jung
Currently, there is no method to update existing table information at
CatalogStore. So, if user execute an insert query, tajo drop a table and then
tajo create a table. It doesn't matter to tajo own CatalogStore like
DerbyStore, MySQLStore. But it is a critical issue to HCatalogStore. if tajo
drop a existing partitioned table, users will lose existing partition
informations. As a result, they should repair table partition against their
will. As you know, hive msck command can affect hive metastore performance.
