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
versioncommand 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.
