Robert Surówka commented on HIVE-2510:
--------------------------------------
I see. Could you point me to where in code this "create table call to
MetaStore" is done?
If it is done at the moment of executing a task, I think it will be better to
check for existence of the database 2 times - once at the moment of Semantic
Analysis and once during the transaction. The reason is, if database doesn't
exist from the beginning we can faster tell user about it and we use less
resources (especially if table is created as select). Furthermore the
null-pointer exception this Jira is about is thrown before the task starts
execution, so if that check for database existence was only during the task
execute, we would need to "wrap" that null pointer exception and "carry it"
until that moment.
