An Ambari Stack for HDP Visualizer for component services

Ambari stack/view for easily installing and managing HDP Visualizer, inspired by Twitter's HDFS du on HDP cluster

  • Download HDP 2.2 sandbox VM image (Sandbox_HDP_2.2_VMware.ova) from Hortonworks website
  • Import Sandbox_HDP_2.2_VMware.ova into VMWare and set the VM memory size to 8GB
  • Now start the VM
  • After it boots up, find the IP address of the VM and add an entry into your machines hosts file e.g.
192.168.191.241 sandbox.hortonworks.com sandbox
  • Connect to the VM via SSH (password hadoop), correct the /etc/hosts entry and start Ambari server
ssh root@sandbox.hortonworks.com
  • Edit /etc/hosts on sandbox and change localhost entry to point to IP address instead of 127.0.0.1 e.g.
127.0.0.1               localhost.localdomain
192.168.191.142 sandbox.hortonworks.com sandbox ambari.hortonworks.com localhost
  • Start Ambari service
/root/start_ambari.sh
  • Install Maven
mkdir /usr/share/maven
cd /usr/share/maven
wget http://mirrors.koehn.com/apache/maven/maven-3/3.2.5/binaries/apache-maven-3.2.5-bin.tar.gz
tar xvzf apache-maven-3.2.5-bin.tar.gz
ln -s /usr/share/maven/apache-maven-3.2.5/ /usr/share/maven/latest
echo 'M2_HOME=/usr/share/maven/latest' >> ~/.bashrc
echo 'M2=$M2_HOME/bin' >> ~/.bashrc
echo 'PATH=$PATH:$M2' >> ~/.bashrc
export M2_HOME=/usr/share/maven/latest
export M2=$M2_HOME/bin
export PATH=$PATH:$M2
  • To deploy the stack and view, run below
cd /root
git clone https://github.com/abajwa-hw/hdpviz.git 

cp -R /root/hdpviz/hdpviz_stack /var/lib/ambari-server/resources/stacks/HDP/2.2/services/

IP=$(ifconfig eth0|awk '/inet addr/ {split ($2,A,":"); print A[2]}')
sed -i "s/sandbox.hortonworks.com/$IP/g" /root/hdpviz/hdpviz-view/src/main/resources/index.html

cd /root/hdpviz/hdpviz-view
mvn clean package
cp target/*.jar /var/lib/ambari-server/resources/views

sudo service ambari restart
  • Then you can click on 'Add Service' from the 'Actions' dropdown menu in the bottom left of the Ambari dashboard:

On bottom left -> Actions -> Add service -> check HDPVIZ server -> Next -> Next -> Next -> Deploy Image

  • On successful deployment you will see the HDPVIZ service as part of Ambari stack and will be able to start/stop the service from here: Image

  • When you've completed the install process, HDPVIZ will appear in Ambari. You can see the parameters you configured under 'Configs' tab Image

  • One benefit to wrapping the component in Ambari service is that you can now monitor/manage this service remotely via REST API

export SERVICE=HDPVIZ
export PASSWORD=admin
export AMBARI_HOST=sandbox.hortonworks.com
export CLUSTER=Sandbox

#get service status
curl -u admin:$PASSWORD -i -H 'X-Requested-By: ambari' -X GET http://$AMBARI_HOST:8080/api/v1/clusters/$CLUSTER/services/$SERVICE

#start service
curl -u admin:$PASSWORD -i -H 'X-Requested-By: ambari' -X PUT -d '{"RequestInfo": {"context" :"Start $SERVICE via REST"}, "Body": {"ServiceInfo": {"state": "STARTED"}}}' http://$AMBARI_HOST:8080/api/v1/clusters/$CLUSTER/services/$SERVICE

#stop service
curl -u admin:$PASSWORD -i -H 'X-Requested-By: ambari' -X PUT -d '{"RequestInfo": {"context" :"Stop $SERVICE via REST"}, "Body": {"ServiceInfo": {"state": "INSTALLED"}}}' http://$AMBARI_HOST:8080/api/v1/clusters/$CLUSTER/services/$SERVICE
  • To remove the HDPVIZ service:

    • Stop the service via Ambari

    • Delete the service

      curl -u admin:admin -i -H 'X-Requested-By: ambari' -X DELETE http://sandbox.hortonworks.com:8080/api/v1/clusters/Sandbox/services/HDPVIZ

    • Remove artifacts

      /var/lib/ambari-server/resources/stacks/HDP/2.2/services/hdpviz-stack/remove.sh
