Cloudera Data Science Workbench Demo Environment

Install scripts of Cloudera Data Science Workbench (CDSW) with CDH secure cluster on cloud. This is for Demo purposes only. Don't use for production.

Note: Please use the stable releases instead of master. https://github.com/takabow/cdsw-demo-env/releases/

  • These scripts install and deploy the following environment automatically.

    • Cloudera Data Science Workbench 1.1.1 (Trial)
    • Cloudera Enterprise 5.12 (Trial)
    • MIT-KDC

  • I only tested on following environments

    • AWS ap-northeast-1 (Tokyo) region
    • Cloudera Director 2.5 on Mac

Requirement

How to use

  1. You need to install Cloudera Director Server/Client on your localhost and accessible by localhost:7189

  2. Copy your-aws-info.conf.template and create your own your-aws-info.conf with

  • AWS_REGION
  • AWS_SUBNET_ID
  • AWS_SECURITY_GROUP
  • KEY_PAIR
  • AWS_AMI
  1. Set AWS_ACCESS_KEY_ID/AWS_SECRET_ACCESS_KEY and run cloudera-director bootstrap-remote command. It takes about 30 minutes.
$ export AWS_ACCESS_KEY_ID=<your-aws-access-key>
$ export AWS_SECRET_ACCESS_KEY=<your-aws-secret>
$ cloudera-director bootstrap-remote cdsw-secure-cluster.conf --lp.remote.username=admin --lp.remote.password=admin --lp.remote.hostAndPort=localhost:7189

Note Only one cluster can be creted on the same network same time using this script. Because bootstrap-configure-network.sh script using nmap tricks to identify the CM (KDC) node during the bootstrapping phase. For the same reason, using this script in a large network (e.g. /16) is bad idea.

  1. ./get_cluster_ip.sh <cluster.conf> provides the connection information to the environment. See also the following Example section.

  2. To terminate this environment, run cloudera-director terminate-remote command.

$ cloudera-director terminate-remote cdsw-secure-cluster.conf --lp.remote.username=admin --lp.remote.password=admin --lp.remote.hostAndPort=localhost:7189

Example

$ export AWS_ACCESS_KEY_ID=<your-aws-access-key>
$ export AWS_SECRET_ACCESS_KEY=<your-aws-secret>

$ cloudera-director bootstrap-remote cdsw-secure-cluster.conf --lp.remote.username=admin --lp.remote.password=admin --lp.remote.hostAndPort=localhost:7189

After above, you can access to http://cdsw.10.0.0.90.xip.io (IP 10.0.0.90 changes every time) from your web browser via SSH SOCKS Proxy (See https://www.cloudera.com/documentation/director/latest/topics/director_security_socks.html).

How to use CDSW

  • Access to CDSW from browser.
  • Click "Sign Up for a New Account" and create a new account. This username doesn't relate to existing OS users or Kerberos principals. Therefore you can create any users.
    • e.g.)
    • Full Name: Demo User1
    • Username: user1
    • Email: [email protected]
    • Password: user1user1
  • After logging in, authenticate against your cluster’s Kerberos KDC by going to the top-right dropdown menu and clicking Settings -> Hadoop Authentication. You can use the prepared principals user1@HADOOP and so on. Please read the following "Users and Authentication" section.
    • e.g.)
    • Principal: user1@HADOOP
    • Password: user1

Users and Authentication

  • OS and CDH users, principals
    • Demo users are created in the postcreate-common-addusers-and-principals.sh script.
    • By default, this script creates five demo users and principals.
    • username/password = user1/user1, user2/user2, user3/user3, admin1/admin1, admin2/admin2
    • admin1 and admin2 are in the same group dba.
    • The realm name creating by this script is HADOOP.
  • Cloudera Manager/Cloudera Navigator
    • username/password = admin/admin
  • CDSW users
    • You need to create CDSW user when you access to CDSW from your browser.

CDSW w/ GPU Support

If you want to use GPU from CDSW, you can use cdsw-gpu-secure-cluster.conf instead of cdsw-secure-cluster.conf

$ cloudera-director bootstrap-remote cdsw-gpu-secure-cluster.conf --lp.remote.username=admin --lp.remote.password=admin --lp.remote.hostAndPort=localhost:7189

By default, this conf boot up p2.xlarge instance.

You also need to create a custom CUDA-capable Engine Image. https://www.cloudera.com/documentation/data-science-workbench/latest/topics/cdsw_gpu.html#custom_cuda_engine

I already built a sample CUDA-capable engine image. If you want to use my image (takabow/cdsw-cuda:2) instead of base engine, you can add the image by going to the top-right dropdown menu and clicking Admin -> Engines -> Engine Images.

For more details, please read the following document. https://www.cloudera.com/documentation/data-science-workbench/latest/topics/cdsw_gpu.html

EC2 Instances

If you change instance type, you can modify first section of cdsw-secure-cluster.conf. But I think these instances are almost minimal.

INSTANCE_TYPE_CM:        t2.xlarge    #vCPU 4, RAM 16G
INSTANCE_TYPE_MASTER:    t2.large     #vCPU 2, RAM 8G
INSTANCE_TYPE_WORKER:    t2.large     #vCPU 2, RAM 8G
INSTANCE_TYPE_CDSW:      t2.2xlarge   #vCPU 8, RAM 32G

WORKER_NODE_NUM:         3            #Number of Worker Nodes

CDSW_DOCKER_VOLUME_NUM:  3
CDSW_DOCKER_VOLUME_GB:   200

CDSW node

On the CDSW node, you can check the status of CDSW using cdsw status. The following example is the status of cdsw tatus after installation finished.
