-------------------------------------
Summary: Fix merge to work in presents of AST rewrites
Key: HIVE-15970
URL: https://issues.apache.org/jira/browse/HIVE-15970
Project: Hive
Issue Type: Bug
Components: Transactions
Affects Versions: 2.2.0
Reporter: Eugene Koifman
Assignee: Eugene Koifman
Priority: Critical
The issue is that Context.getDestNamePrefix() caches ASTNode objects to figure
out if a given insert branch of multi-insert is insert, update or delete but
objects change when the tree is modified. For example,
row-filtering/column-masking does this, but also other optimizations/features.
