@mike_bronson7 The similar discussion happened on one of other Community thread by @Shelton You can follow this here: https://community.cloudera.com/t5/Support-Questions/add-new-data-node-to-existing-cluster/td-p/213133 Also the decommissioning is more suitable approach you can see this doc more more details though: https://docs.cloudera.com/HDPDocuments/Ambari-2.7.3.0/managing-and-monitoring-ambari/content/amb_manage_components_on_a_host.html

@mike_bronson7 I meant to say there is not a bunch of people using package install because of following reason[1]: Cloudera does not support clusters that are not deployed and managed by Cloudera Manager. If you choose to install CDH manually using these instructions, you cannot use Cloudera Manager to install additional parcels. This can prevent you from using services that are only available via parcel. For testing purpose you are free to choose any method but it depends what you are looking i.e easy managing of cluster using CM web UI or just want to play with a demo installation. Regarding the end of life question, Yes that's the nature of software support that end of the day it will be end of life after some years. For Cloudera software support cycle you can here is a glance: https://www.cloudera.com/legal/policies/support-lifecycle-policy.html Cheers!

You can try to use this command : http://<ambari-server>:8080/api/v1/stacks/{stackName}/versions/{stackVersion}/services To get help on API calls use this : http://<ambari-server>:8080/api-docs. You can try out api calls to understand what api returns.

@mike_bronson7 It is recommended to have minimum 3 data nodes in the cluster to accommodate 3 healthy replicas of a block as the default replication factor is 3. HDFS will not write replicas of same blocks on the same data node. In this scenario there will be under replicated blocks and 2 healthy replicas will be placed on the available 2 data nodes.

Hello @mike_bronson7 , Thank you for posting your query You can execute 'get' on the same zookeeper client shell for the znode you would be able to get the hostname Example: zookeeper-shell.sh zoo_server1:2181 <<< "ls /brokers/ids/1018" It returns output as follows (example - in my case) [zk: localhost:2181(CONNECTED) 5] get /brokers/ids/10 {"listener_security_protocol_map":{"PLAINTEXT":"PLAINTEXT"},"endpoints":["PLAINTEXT://simple01.cloudera.com:9092"],"jmx_port":9393,"host":"simple01.cloudera.com","timestamp":"1590512066422","port":9092,"version":4} cZxid = 0x1619b ctime = Tue May 26 09:54:26 PDT 2020 mZxid = 0x1619b mtime = Tue May 26 09:54:26 PDT 2020 pZxid = 0x1619b cversion = 0 dataVersion = 1 aclVersion = 0 ephemeralOwner = 0x1722ddb1e844d50 dataLength = 238 numChildren = 0 so, my brokerID 10 is mapped with the host: simple01.cloudera.com

@mike_bronson7 You can achieve it in a similar way described on the following thread: https://community.cloudera.com/t5/Support-Questions/AMBARI-how-to-set-value-in-json-REST-API/td-p/290385 Example: AMBARI_FQDN=newhwx1.example.com
CLUSTER_NAME=NewCluster
DATANODES=newhwx1.example.com,newhwx2.example.com,newhwx3.example.com,newhwx5.example.com
# curl -s -u admin:admin -H "X-Requested-By: ambari" -X PUT -d '{"RequestInfo":{"context":"Stop DataNodes","operation_level":{"level":"SERVICE","cluster_name":"'"$CLUSTER_NAME"'"},"query":"HostRoles/component_name=DATANODE&HostRoles/host_name.in('$DATANODES')&HostRoles/maintenance_state=OFF"},"Body":{"HostRoles":{"state":"INSTALLED"}}}' "http://$AMBARI_FQDN:8080/api/v1/clusters/$CLUSTER_NAME/host_components" . .

@mike_bronson7 This like talks about the command link options to Stop various HDP components manually using CLI. (Including HS2 and Hive Metastore) https://docs.cloudera.com/HDPDocuments/HDP2/HDP-2.6.5/bk_reference/content/stopping_hdp_services.html
