ambari-server unable to start after upgrading from 2.5.3 to 2.6

[#1]

Hi all,

The ambari-server is upgraded from 2.5.3 to 2.6 in my cluster. The repository is visible and updated ambari rpm through yum.

The ambari-server setup went smooth and "completed successfully".

The ambari-server start command fails to start ambari by, Unable to determine server PID and Ambari Server java process died with exitcode 255.

Full error message is shown below:

This error indicates that you have installed Ambari Server Binary 2.6 using "yum upgrade ambari-server", But your Ambari Database has Schema version 2.5.2

Current database store version is not compatible with current server version, serverVersion=2.6 .0.0, schemaVersion=2.5.2 at 

.

So please make sure that you run the following command first to upgrade the Ambari DB schema which is pointing to 2.5.2

# ambari-server upgrade
# ambari-server start

.

Ambari server upgrade command will upgrade the Ambari DB schems (which is currently having the 2.5.2 version pointing inside it's "metainfo" table will also be updates along with other table schema upgrade on Ambari DB.
