Description

Currently, DOCKER_IMAGE_PATTERN in DockerContainerExecutor can only match docker images with the path like "sequenceiq/hadoop-docker:2.6.0", which has only 1 "/" in the path.

public static final String DOCKER_IMAGE_PATTERN = "^(([\\w\\.-]+)(:\\d+)*\\/)?[\\w\\.:-]+$";

In our cluster, the image name have multi layers, such as "docker-registry:8080/cloud/hadoop-docker:2.6.0", which is workable when using "docker pull IMAGE_NAME", but can not pass the check of image name in saneDockerImage().
