Subject [jira] [Commented] (YARN-3324) TestDockerContainerExecutor should clean test docker image from local repository after test is done
Date Sat, 28 Mar 2015 06:30:53 GMT

    [ https://issues.apache.org/jira/browse/YARN-3324?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14385160#comment-14385160

Ravindra Kumar Naik commented on YARN-3324:
-------------------------------------------

{quote}The overhead of downloading the image every time can be neglected if we have private
docker registry in LAN. It could be a problem if thousands of machine pull image from a single
registry at the same time.{quote} 
Agreed

{quote}If we do not delete downloaded images after test, to avoid images accumulation, we
should guarantee docker image related tests only use limited types of images.{quote}
The tests currently use a single type of image. May be we can write a note in the tests so
anyone who modifies the test in future takes a note to revisit this issue if more images are
used in test

> Current TestDockerContainerExecutor only cleans the temp directory in local file system
but leaves the test docker image in local docker repository. It should be cleaned.
