Hadoop in a Slice

We are actively updating this tutorial. If you need help with this tutorial please contact: help@geni.net

Part I: Obtain Resources: create a slice and reserve resources

Image Map

Instructions

1. Create a slice

  1. Login to https://portal.geni.net
  2. Create a new slice in one of your projects
  3. Launch Jacks (use the beta version available in the GENI portal )
  4. Click "Add Resources"

2. Bind the Slice

  1. Click "Site 0" in the Jacks window
  2. Select an ExoGENI site (If you are participating in an organized tutorial, please bind the VMs to the rack assigned to you)
Bind the Slice

3. Create the Hadoop Master

  1. Add an ExoGENI VM to your slice.
  2. Add the Hadoop Master
  1. Select the VM to set its properties:
    1. Name: hadoop-master
    2. Node Type: ExoGENI Medium
    3. Set the Master Name
    4. Custom Disk Image Name: http://geni-images.renci.org/images/standard/hadoop/hadoop_debian6.v1.0/hadoop_debian6.v1.0.xml
    5. Disk Image Version: 54ddc5ed7d4a22331651d7b78dc5d39138f8a165
    6. Set the Master Image
    7. Add an Install Script:
      URL: http://geni-images.renci.org/images/tutorials/GENI-hadoop/master.sh
      Path: /tmp
    8. Set the Master Install Script
    9. Add an execute service to execute the script at boot time:
      chmod +x /tmp/master.sh; /tmp/master.sh
    10. Set the Master Execute Scripts

3. Create the Hadoop Workers

  1. Add a 2 more VMs to the same rack as the first VM.
Set the Master Execute Scripts
  1. Edit each worker’s attributes
    1. Names: hadoop-worker-0 and hadoop-worker-1
    2. Node Type: ExoGENI Medium
    3. Set the Master Execute Scripts
    4. Disk Image Name: http://geni-images.renci.org/images/standard/hadoop/hadoop_debian6.v1.0/hadoop_debian6.v1.0.xml
    5. Disk Image Version: 54ddc5ed7d4a22331651d7b78dc5d39138f8a165
    6. Set the Master Execute Scripts
    7. Add an Install Script:
      URL: http://geni-images.renci.org/images/tutorials/GENI-hadoop/worker.sh
      Path: /tmp
    8. Set the Master Execute Scripts
    9. Add an execute service to execute the script at boot time. For each VM, substitute the VM’s name for where the following uses “hadoop-worker-0”. (Note: the following should be placed on one line)
      chmod +x /tmp/worker.sh; /tmp/worker.sh $hadoop-master.Name() $hadoop-master.IP("link-0") $hadoop-worker-0.Name() $hadoop-worker-0.IP("link-0")
    10. Set the Master Execute Scripts
    11. Repeat for worker 1
    12. Set the Master Execute Scripts

4. Create the Network

  1. Link all three VMs with a broadcast network
  2. Set the Master Execute Scripts
    1. Set the master's IP to 172.16.1.1
    2. Set the master's netmask to 255.255.255.0
    3. Set the Master Execute Scripts
    4. Set the worker0's IP to 172.16.1.10
    5. Set the worker0's netmask to 255.255.255.0
    6. Set the worker1's IP to172.16.1.11
    7. Set the worker1's netmask to 255.255.255.0

5. Instantiate the Slice

You can use any tool to reserve this topology, today we are going to use Omni. To do that you will need to:

  1. Download the rspec and save it to your local disk by clicking the download button
  2. Submit the request by running this omni command in a command line window:
    omni createsliver slicename rspec_filename -a AM_NICKNAME
  3. Wait until the slice is up
  4. Log into the master node
