HDP multinode installation using Ambari Blueprints with Kerberos.

##This is tested in a CentOS 7 64 Bit Servers hosted in Digital Ocean

Note that the hostnames are as below -

• node01.hadoophdp.com
• node02.hadoophdp.com
• node03.hadoophdp.com

node01.hadoophdp.com acts as the ambari server.

On node01, execute the script - setup-ambari-server.sh

On node02, node03, execute the script - setup-ambari-agent.sh

At this point ambari-agent’s are not started. Ensure DNS/Rev. DNS is working among the nodes, else modify /etc/hosts on all hosts as per your IP’s

In my case, I updated /etc/hosts

Start Ambari Server

Start Ambari Agent on all the hosts

Ensure ambari-server and ambari-agent’s are running

Follow the below steps on Ambari-server -

  yum install git -y
  git clone https://github.com/hemantdindi/hdp-ambari-blueprints.git
  cd hdp-ambari-blueprints/multinode-with-kerberos/json/
  chmod +x *
  ./configure-scripts.sh
  ./registerBluePrint.sh

You should a output similar to this -

  [root@node01 json]# ./registerBluePrint.sh
  {
    "href" : "http://node01.hadoophdp.com:8080/api/v1/clusters/hdp25mn/requests/1",
    "Requests" : {
      "id" : 1,
      "status" : "Accepted"
    }
  }

If all goes well, login to ambari and you will see the progress similar as below -
