Chapter II.6. Appendix: Upgrading the HDP Stack from 1.3.2 or later to 2.0.6

The stack is the coordinated set of Hadoop components that you have installed. If you have a current instance of the 1.3.2 or later stack that was installed and managed by Ambari that you want to upgrade to the new 2.0.6 version of the stack and to also upgrade to the 1.4.1 version of Ambari Server and Agents, use the following instructions. This insures that the upgraded stack can still be managed by Ambari.

	Note
	If you have turned on Security (Kerberos) for your installation, you should turn it off before the upgrade. On Ambari Web->Admin view->Security-> click Disable Security. You can re-enable after the upgrade.

If you are upgrading from any other 1.x version of the stack, you must upgrade to 1.3.2 or later before you can upgrade to 2.0.6. See Upgrading the HDP Stack to 1.3.3 for more information. Upgrades from previous versions of 2.x are not supported.

	Note
	If you have already upgraded to Ambari Server 1.4.1 and just want to upgrade the HDP stack, you can skip Section 2 and Section 3.
