Chandni Singh updated YARN-9378:
--------------------------------
Description:
Refer YARN-3854.
Add Docker Image Localizer. The image localizer is part of
{{ResourceLocalizationService}}. It serves the following purpose:
1. All image localization requests will be served by image localizer.
2. Image localizer initially runs {{DockerImagesCommand}} to find all images on
the local node.
3. For an image localization request, it executes {{DockerPullCommand}} if the
image is not present on the local node.
4. It returns the status of image localization by periodically executing
{{DockerImagesCommand}} on a particular image.
{{LinuxContainerExecutor}} is for container operations. DockerImagesCommand is
independent of any container. The image localizer acts as a service that will
localize docker images and maintain an image cache. Other components can use
this to query about the images on the node.
