--------------------------------

             Summary: Detect query rewrite scenario for UPDATE/DELETE/MERGE and fail fast
                 Key: HIVE-15891
                 URL: https://issues.apache.org/jira/browse/HIVE-15891
             Project: Hive
          Issue Type: Bug
          Components: Transactions
    Affects Versions: 2.2.0
            Reporter: Wei Zheng
            Assignee: Wei Zheng


Currently ACID UpdateDeleteSemanticAnalyzer directly manipulates the AST tree but it's different
from the general approach of modifying the token stream and thus will cause AST tree mismatch
if there is any rewrite happening after UpdateDeleteSemanticAnalyzer.

The long term solution will be to rewrite the AST handling logic in UpdateDeleteSemanticAnalyzer,
to make it consistent with the general approach.

This ticket will for now detect the error prone cases and fail early.
