[jira] [Created] (HIVE-24315) Improve validation and semantic analysis in HPL/SQL

Attila Magyar created HIVE-24315:
------------------------------------

             Summary: Improve validation and semantic analysis in HPL/SQL 
                 Key: HIVE-24315
                 URL: https://issues.apache.org/jira/browse/HIVE-24315
             Project: Hive
          Issue Type: Improvement
          Components: hpl/sql
            Reporter: Attila Magyar
            Assignee: Attila Magyar


There are some known issues that need to be fixed. For example it seems that arity of a function is not checked when calling it, and same is true for parameter types. Calling an undefined function is evaluated to null and sometimes it seems that incorrect syntax is silently ignored. 

In cases like this a helpful error message would be expected, thought we should also consider how PL/SQL works and maintain compatibility.
