Ambari Blue Print :- How to install the exact stack version.

[#1]

If you need to install the specific version of HDP using Blue prints use the Following steps.

• Install ambari-server and ambari-agent and register it.
• Use the appropriate os version. Here I have used the os version as centos/redhat 7
• Make sure you do it on a clean host with no existing hadooppackages etc.

Create 4 files under say /root

[root@vijaybluetest1 ~]# ls

blueprint.json cluster.json repo.json utils.json

blueprint.json :- Contains cluster definition.

1) cat blueprint.json

{

"host_groups" : [

{ "name":"host_group_1",

"components":[

{ "name" : "NODEMANAGER" },

{ "name" : "DATANODE" },

{ "name" : "ZOOKEEPER_SERVER" },

}

],

2) cat repo.json

{

"Repositories":{

"base_url":"http://public-repo-1.hortonworks.com/HDP/centos7/2.x/updates/2.5.3.0",

"verify_base_url":true

}
