Perform the Upgrade
To upgrade your HDP version:
Steps
Log in to Ambari.
Browse to Cluster Admin > Stack and Versions.
Click the Versions tab.
The registered and installed target HDP version displays an Upgrade button.
Click Upgrade on the target version.
Based on your current HDP version and the target HDP version, Ambari performs a set of prerequisite checks to determine if you can perform a rolling or an express upgrade. A dialog displays the options available.
Select the Express Upgrade method. (Only supported method for upgrading from HDP 2.6 to 3.1.5)
Advanced options are also available.

Ambari automatically skips any Service Check failures and completes the task without requiring user actions. After all the Service Checks have run in a task, you see a summary of the failures and options to continue the upgrade or pause.
- Skip all Slave Component failures
Ambari automatically skips any Slave Component failures and completes the task of upgrading Slave components without requiring user actions. After all Slave Components have been upgraded, you see a summary of the failures and options to continue the upgrade or pause.
