9.3. Validation

To validate the upgrade process for Hadoop, HBase, Phoenix, and Mahout clients, submit related smoke tests (see Appendix A).

To validate the Sqoop upgrade:

  • Run the Sqoop smoke test.

  • Invoke a Sqoop command and make sure that it responds correctly.

  • The Sqoop version command should return the correct version.

If the upgrade process fails, follow the steps in Downgrading the Cluster, starting with "Downgrade clients on cluster (core and non-core) components." Otherwise, continue with the next upgrade step.
