Pseudo Distributed Setup

Lens pseudo-distributed setup is done using docker. Hive server and hadoop daemons are run as separate processes in lens pseudo-distributed setup. Lens docker files are located in

  incubator-lens/lens-docker/lens-test

The above directory contains the lens docker images that can be used for development and testing.

To build the image

  cd tools/scripts
  ./build-docker.sh

Before running the build, docker must be installed in the system. The above script will build the lens docker image and download the dependent images of hive and hadoop.

Steps to run lens docker image

Initialize Boot2Docker

  boot2docker init

Start Boot2Docker

  boot2docker start

You will see an output similar to the one pasted below:

  Waiting for VM and Docker daemon to start...
  .....o
  Started.
  Writing /Users/<user-name>/.boot2docker/certs/boot2docker-vm/ca.pem
  Writing /Users/<user-name>/.boot2docker/certs/boot2docker-vm/cert.pem
  Writing /Users/<user-name>/.boot2docker/certs/boot2docker-vm/key.pem

  To connect the Docker client to the Docker daemon, please set:
      export DOCKER_HOST=tcp://192.168.59.103:2376
      export DOCKER_CERT_PATH=/Users/<user-name>/.boot2docker/certs/boot2docker-vm
      export DOCKER_TLS_VERIFY=1

Export all variables as mentioned in the output on your machine.

Run the image

  $(boot2docker shellinit)
  cd tools/scripts
  ./run-docker.sh

This will start the docker container and the container will have its Lens directories mounted to your actual checked out code, allowing you to modify and recompile your Lens source and have them immediately usable in the docker images (without rebuilding the image).
