Hive Metastore Hook to to fire only on success

[Daniel Haviv <da...@gmail.com>]

Hi,
I'm writing a HMS hook and I noticed that the hook fires no matter if the
operation succeeded or not.
For example, if a user creates an already existing table, the operation
will fail but the the hook will fire regardless.

Is there a way to either validate that the operation succeeded or fire only
upon success?


TY.
Daniel

Thanks.
I was using MetaStoreEventListener and wasn't aware there's another type of
HMS hook.

Which version of Hive are you on and which hook are you seeing fire?  Based
on looking at the master code you should only see the commitCreateTable
hook call if the creation succeeds.
