Some problems caused by hive using asynchronous thread pool to delete tables

[Carol Chapman]

At present, for the operation of deleting a table, hive puts it into a thread pool to execute asynchronously, and does not receive the execution result. In some extreme cases, when deleting a table fails, it may cause problems in the subsequent SQL execution.

I guess this is the way people would use Hive, where such an operation like deleting tables can fail at any time.

However, the current situation is that hive will not notify the user if deleting the table fails, which may cause some trouble
