Hi, @Emilio Lopez, The agent log looks OK, it's sending hearbeats with different "id" each time. Please take a look at the contents of /var/lib/ambari-agent/data -- look for output*txt which contain "Host checks started.", and corresponding error*txt files (eg. output-2.txt and error-2.txt). Those might have some info about the problem. Also search for check_host in ambari-agent.log.

Adding the above to ambari.properties and creating the certificate file jwt-cert.pem has the same effect as running ambari-server setup-sso interactively. For complete list of properties, including "advanced" ones, see https://github.com/apache/ambari/blob/release-2.6.0/ambari-server/src/main/python/ambari_server/setupSso.py

If I understand correctly, you create a cluster using some initial blueprint, change some configuration parameters for services, and would like to get a blueprint with the updated parameters? If so, then you need to export the blueprint from the cluster, which is explained eg. in this answer.

Hi @uri ben-ari, Your link and example are about IBM UrbanCode Deploy, not Apache Ambari. Blueprints in Ambari are immutable, cannot be updated. You can POST the updated blueprint with a new name and use that to deploy the cluster.

@Daniel Müller look for these properties (the ones present in hive-site.xml) on Hive's config page, not Spark, within Ambari.
