Review comment:
In apache/master, we have "SELECT 'Upgrading MetaStore schema from 2.1.0 to
2.2.0' AS MESSAGE;" which shouldn't have the issue as per description in jira.
I think, skipping the row based on null values is incorrect as it may have
any other side effect.

> 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. The issue is coming with mysql version 5.7 and above.
