Check SERDE Definitions and Availability

Ensure correct Serde definitions and a reference to a SERDE exists to ensure a successful upgrade.

You perform this step if you do not modify the HSMM process for expediting the Hive upgrade.
  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.
