we have ambari cluster and HDP version 2.6.5
we want to add the service OOZIE on specific nodes in our cluster
for example - we have 10 workers machines in the HDP cluster
so we want to add he service OOZIE on each worker machine
from documentation we found the following API that really add the service to ambari
curl --user admin:admin -H "X-Requested-By: ambari" -i -X POST -d '{"ServiceInfo":{"service_name":"OOZIE"}}' http://localhost:8080/api/v1/clusters/HDP/services
but we not succeeded to improve the API in order to install the service OOZIE on each worker node
the final target is to add the service to amabri while each worker node in amabri should have the service OOZIE
any ideas how to continue from this stage?

little question why just not stop the service - HDFS on each new data node and set it to maintenance mode ?

hi all we have HDP 2.6.4 cluster with 245 workers machines each worker have ( datanode and resource manager ) we want to add 10 new workers machines to the cluster but we want to disable the datanode machines so no data will transfer from the old datanodes to the new datanodes I thinking to do maintenance mode on the new datanode , but not sure if this action is enough in order to disable the datanodes machine on the new workers

hi all We are performing now the change hostname configuration on production cluster according to the document - https://docs.cloudera.com/HDPDocuments/Ambari-2.7.0.0/administering-ambari/content/amb_changing_host_names.html The last stage is talking about – "in case NameNode HA enabled , then need to run the following command on one of the name node" hdfs zkfc -formatZK -force since we have active name node and standby name node we assume that our namenode is HA enable ? but we want to understand what are the risks when doing the following cli on one of the namenode hdfs zkfc -formatZK -force is the below command is safety to run without risks ?

thank you for the post but another question - according to the document - https://docs.cloudera.com/HDPDocuments/Ambari-2.7.0.0/administering-ambari/content/amb_changing_host_names.html The last stage is talking about – in case NameNode HA enabled , then need to run the following command on one of the name node hdfs zkfc -formatZK -force thank you for the post but since we have active name node and standby name node we assume that our namenode is HA enable example from our cluster but we want to understand what are the risks when doing the following cli on one of the namenode hdfs zkfc -formatZK -force is the below command is safety to run without risks ?

We have HDP cluster version `2.6.5` and ambari `2.6.1` version
Cluster include 3 masters machines , and 211 data-nodes machines ( workers machines ) , all machines are `rhel 7.2` version
Example
master1.sys77.com , master2.sys77.com , master3.sys77.com …
And data nodes machines as
worker01.sys77.com , worker02.sys77.com ----> worker211.sys77.com
Now we want to change the domain name to `bigdata.com` instead of `sys77.com`
What is the procedure to replace the `domain name` (`sys77.com`) for Hadoop cluster ? ( HDP cluster with ambari )
