Check co-processor classes
External co-processors are not automatically upgraded, you must upgrade them manually. Before upgrading, ensure that your co-processors are compatible with the upgrade.
There are two ways to handle co-processor upgrade:
- Upgrade your co-processor jars manually before continuing the upgrade.
- Temporarily unset the co-processors and continue the upgrade.
Once they are manually upgraded, they can be reset.
Attempting to upgrade without upgrading the co-processor jars can result in unpredictable behaviour such as HBase role start failure, HBase role crashing, or even data corruption.
Continue the upgrade using the Cloudera Manager upgrade wizard.
