Subject [jira] Commented: (HIVE-1936) hive.semantic.analyzer.hook cannot have multiple values
Date Sat, 29 Jan 2011 01:14:44 GMT

Ashutosh Chauhan commented on HIVE-1936:
----------------------------------------

Not really. I was just wondering why would you want to do it in a series of hooks, rather
then doing all of it in one hook, because it seems list must all always be complete and hooks
in that list aren't going to be optional. 
Regardless of that, I had the similar requirement and what I had done was to have a top level
hook, which keeps a list of hook with it and invokes an appropriate hook depending on the
parse tree and context. Depending on what you are trying to achieve that may or may not work
in your case. I can point you to code for it, in case you want to take a look.
