          Issue Type: Bug
          Components: HCatalog
    Affects Versions: 2.2.0, 3.0.0
            Reporter: Mithun Radhakrishnan
            Assignee: Mithun Radhakrishnan


When a table's schema evolves to add a new member to a struct column, Hive queries work fine, but {{HCatLoader}} breaks with the following trace:
