Wei Zheng reassigned HIVE-15891:
--------------------------------
> 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.
