For test and developement purposes on your laptop, there is no specifics upon the existing installation instructions of the Spitfire Docker image. Optionally, ou can also install the Spitfire bundled with Ambari Docker image.
For scalable deployments on the Microsoft Azure Cloud, we detail in the following sections the steps to set you-up.
We assume you have an operational Azure account and that you are used to provision resources like virtual images, virtual network….
You are also able to connect remotely to those images via SSH and run Linux shell commands.
I you don’t have yet an account, Microsoft can provide you with a free trial subscription.
We describe 2 different techniques:
The first one is an easy installation from the Microsoft Azure Marketplace. The current available version is however limited in terms of scalability, this is why we recommend to use the second way.
The second one is a separate installation of a Microsoft Azure HDInsight (Hadoop) cluster and the installation of the Spitfire Docker image on a separated virtual machine instance located on the same virtual network.
Just go to the Datalayer page on the Microsoft Azure Marketplace and click on install.
You will then have to fill a few parameters like the size of the instance…, and then click on
Once done, check the public IP address which has been assigned and browse the welcome page served on that IP address.
This deployment supports Scala, Python and R in
First create a dedicated Resource Group for your future Cluster and any upcoming servers you will add.
In this Resource Groupe, create a dedicated Virtual Network for you Cluster and any upcoming servers you will add.
Launch a new HDInsigh Cluster.
Hadoop cluster type is the one you need (not Spark, as the Spitfire image will ship the needed Spark Libraries to the Hadoop Cluster in YARN mode).
As second step, define the credentials.
Then choose the number of nodes you want. A tiny 3 nodes cluster will do the job to start.
Configure the network and the resource group (indicate the ones you have created in the previous steps).
Follow the operation events. If something goes wrong, delete and restart…
If everything goes well, your Hadoop cluster will be available in the Resource Group you have defined.
You can verify that your Head and Worker nodes are available on the Virtual Network you have created.
The public IP adresses with which you will connect to from your remote environment are also listed.
You can connect via SSH to the Head Node.
This section explains how to create a separate node for Spitfire.
First, choose a server type (for example a Centos 7 image).
Set the needed parameters:
Double check that everything is nicely setup.
For the network WEB access to Spitfire, open port
80 for HTTP.
From a shell session, use the SSH command to connect to the Spitfire node by providing the username and IP address .
If you used a password for the user account, you will be prompted to enter the password.
If you used an SSH key that is secured with a passphrase, you will be prompted to enter the passphrase. Otherwise, SSH will attempt to automatically authenticate by using one of the local private keys on your client.
Once logged on, the first action is to Act as
Then install and start Docker. If you use a Centos 7 image, this can be achieved with:
sudo yum install -y docker sudo service docker start
If you use a Ubuntu image, you will install and start Docker with:
sudo apt-get install docker.io sudo service docker start
We the expect you to:
Get the image with
docker pull datalayer/spitfire.
start.sh script located in the
spitfire folder will allow you to start the
Datalayer Spitfire server.
For more details, follow the Spitfire Docker documentation to install and configure the needed Spitfire Docker image. Check especially the
Spark in YARN mode section as the Docker container will have to connect to the external HDInsight cluster.
Before launching Spitfire, there are 2 important additional steps to connect to the correct cluster:
Copy the complete
/etc/hadoop/conf folder from the HDInsight cluster Head Node to the Spitfire Node. You will scp them on your laptop from the HDInsight cluster, to then scp them from your laptop to the Spitfire Node
/etc/hosts and add the entries present in the
/etc/hosts of the HDInsight cluster Head Node (connect via SSH to see the host file).
Typical entries in
/etc/hosts are e.g.:
100.117.108.74 PkrVMxrkvxp812q.PkrSrvxrkvxp812q.b2.internal.cloudapp.net PkrVMxrkvxp812q 10.0.0.17 10.0.0.17 headnodehost # SlaveNodeManager
These are the steps to fit Azure requirements:
datalayer-docker repository you have cloned, go to the
spitfire folder and start on the HTTP port 80 with:
CTRL-C and stop the running Spitfire process with:
/opt/datalayer-spitfire/conf/datalayer-site.xml and set:
<property> <name>datalayer.spark.master.mode</name> <value>yarn</value> </property> <property> <name>datalayer.hadoop.conf.dir</name> <value>/etc/hadoop/conf</value> </property>
Finally take note of the public IP address of your Spitfire Node and type it in your browser. The Spitfire welcome page should show up.
