Change subject: IMPALA-8528: Refactor authorization check in AnalysisContext
......................................................................


Patch Set 6:

(2 comments)

Not quite following the pre/post/context stuff. I'm guessing this will be used 
for audit? Probably cleaner to just keep this to a refactor (moving code 
around) and not also introduce this new "context" concept until it's needed for 
audits?

PS6, Line 423:       authzCtx = authzChecker.preAuthorize(analysisResult_, 
catalog_);
I'm not entirely following the purpose of the pre/post stuff here. Couldn't 
this all be done within the 'authorize()' call itself?

this seems to be a bit more in that it's also supposed to return an 
authorization context
