Check SERDE Definitions and Availability

Incorrect Serde definitions and a reference to a SERDE that does not exist can cause upgrade problems.

  1. Check Serde definitions for correctness and check for SERDE availability.
  2. Correct any problems found as follows:
    • Remove the table having the problematic SERDE.
    • Ensure the SERDE is available during the upgrade, so the table can be evaluated.
