> Error in detecting availability of HiveSemanticAnalyzerHooks
> ------------------------------------------------------------
>
> Key: HIVE-11413
> URL: https://issues.apache.org/jira/browse/HIVE-11413
> Project: Hive
> Issue Type: Bug
> Components: Query Processor
> Affects Versions: 2.0.0
> Reporter: Raajay Viswanathan
> Assignee: Raajay Viswanathan
> Priority: Trivial
> Labels: newbie
>
> In {{compile(String, Boolean)}} function in {{Driver.java}}, the list of
> available {{HiveSemanticAnalyzerHook}} (_saHooks_) are obtained using the
> {{getHooks}} method. This method always returns a {{List}} of hooks.
> However, while checking for availability of hooks, the current version of the
> code uses a comparison of _saHooks_ with NULL. This is incorrect, as the
> segment of code designed to call pre and post Analyze functions gets executed
> even when the list is empty. The comparison should be changed to
> {{saHooks.size() > 0}}.
