Darren Yin created HIVE-8082:
--------------------------------
Summary: generateErrorMessage doesn't handle null ast properly
Key: HIVE-8082
URL: https://issues.apache.org/jira/browse/HIVE-8082
Project: Hive
Issue Type: Bug
Affects Versions: 0.13.1, 0.13.0, 0.12.0, 0.11.0
Environment: anything
Reporter: Darren Yin
Priority: Minor
in SemanticAnalzyer.genUnionPlan, tabref can be null, and if then one of the
"throw new SemanticException" lines gets called, generateErrorMessage will
error out with a NullPointerException when ast.getLine() is called. The fix is
just to add a check for if (ast == null)
