@tcpip001to set hash key in your case you must create an EvaluateJsonPath and add a new attribute for each property that you're using, following your example: For Hash Key: Property: hashKey Value: $.k For Range Key I believe that is the same process: Property: rangeKey Value: $.v And finally go to PutDynamoDb processor and put in the properties: Hash Key Value: ${hashKey} Range Key Value: ${rangeKey} I hope this could help you.

Hi @Dima Kovalyov, I guess its mentioned in hortonworks docs that you need to wget the repo with wget -O /etc/apt/sources.list.d/ambari.list http://public-repo-1.hortonworks.com/ambari/ubuntu16/2.x/updates/2.7.0.0/ambari.list apt-key adv --recv-keys --keyserver keyserver.ubuntu.com B9733A7A07513CAD apt-get update refer to : https://docs.hortonworks.com/HDPDocuments/Ambari-2.7.1.0/administering-ambari/content/amb_download_the_ambari_repository_on_ubuntu_16.html can you please accept the abouve answer if it satisfies your query

Hi @Dima Kovalyov, The "HOSTGROUP" token syntax is not a general-purpose mechanism for resolving hostnames in the configuration for a Blueprint. This syntax is generally used in the following scenarios: 1. Exported Blueprints 2. HA-related Blueprints Outside of these scenarios, the "HOSTGROUP" syntax is not recommended. The Ambari Blueprints configuration processor will attempt to match HOSTGROUP tokens with hostnames for a specific subset of configuration properties, but this subset of properties is a static list, and is not configurable. As you mentioned, it is also true that out-of-stack services are not supported by this syntax, for the reason I've listed above. The "{{ var }}" syntax is not directly supported by the Blueprints processor. There might be cases where a configuration property is pushed down to an ambari-agent that interprets this python-like variable, but this behavior is not guaranteed to work, and should be avoided in Blueprints. Hope this helps. Thanks, Bob

Hi everyone! I installed the ambari server and ambari-agent to my laptop (SuSE Tumbleweed 2019) to set up a local single-node Hadoop cluster. (Server and agent versions 2.1.2.1-418) Server starts without issues, and I can open the console at http://localhost:8080 Agent says it started, but it can't connect the server, here's what the log says : ERROR 2019-07-15 11:06:06,862 NetUtil.py:77 - [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:727)ERROR 2019-07-15 11:06:06,862 NetUtil.py:78 - SSLError: Failed to connect. Please check openssl library versions.Refer to: https://bugzilla.redhat.com/show_bug.cgi?id=1022468 for more details. I have python (2.7.16-2.1) installed. Also python3 is installed, but the executable defaults to version 2.7 : ls -l /usr/bin/python lrwxrwxrwx 1 root root 9 Jun 24 22:12 /usr/bin/python -> python2.7 I would implement this "verify=disable" solution mentioned above, but there is no file named cert-verification.cfg in my system. There is no python dir under etc at all ! So I think maybe python under SuSE might have a different configuration than other distributions. I google'd a lot, but couldn't find a solution for this yet. Can someone guide me thru this issue please ?
