------------------------------------------
Summary: HMS schema Upgrade Script is failing with NPE
Key: HIVE-21844
URL: https://issues.apache.org/jira/browse/HIVE-21844
Project: Hive
Issue Type: Task
Components: HiveServer2
Affects Versions: 4.0.0
Reporter: mahesh kumar behera
Assignee: mahesh kumar behera
Fix For: 4.0.0
schema upgrade tool is failing with NPE while executing "SELECT 'Upgrading
MetaStore schema from 1.2.0 to 2.0.0' AS ' '". The header row (metadata) is
coming with rows having value null. This is causing null pointer access in
function TableOutputFormat::getOutputString when row.values[i] is accessed.
Instead of " AS ' ' ", if some other value like "AS dummy" is given, it's
working fine.
