      Description

      Create a new DockerContainerRuntime that implements support for docker containers via container-executor. LinuxContainerExecutor should default to current behavior when launching containers but switch to docker when requested.

      Overview
      ===
      The current mechanism of launching/signaling containers is moved to its own (default) container runtime. In order to use docker container runtime a couple of environment variables have to be set. This will have to be revisited when we have a first class client side API to specify different container types and associated parameters. Using ‘pi’ as an example and using a custom docker image, this is how you could use the docker container runtime (LinuxContainerExecutor must be in use and the docker daemon needs to be running) :

      export YARN_EXAMPLES_JAR=./share/hadoop/mapreduce/hadoop-mapreduce-examples-*.jar
      bin/yarn jar $YARN_EXAMPLES_JAR pi -Dmapreduce.map.env="YARN_CONTAINER_RUNTIME_TYPE=docker,YARN_CONTAINER_RUNTIME_DOCKER_IMAGE=ashahab/hadoop-trunk" -Dyarn.app.mapreduce.am.env="YARN_CONTAINER_RUNTIME_TYPE=docker,YARN_CONTAINER_RUNTIME_DOCKER_IMAGE=ashahab/hadoop-trunk"  -Dmapreduce.reduce.env="YARN_CONTAINER_RUNTIME_TYPE=docker,YARN_CONTAINER_RUNTIME_DOCKER_IMAGE=ashahab/hadoop-trunk" 4 1000
      

      LinuxContainerExecutor can delegate to either runtime on a per container basis. If the docker container type is selected, LinuxContainerExecutor delegates to the DockerContainerRuntime which in turn uses docker support in the container-executor binary to launch/manage docker containers ( see YARN-3852 ) .
