Subject [jira] [Commented] (YARN-4255) container-executor does not clean up docker operation command files.
Date Tue, 13 Oct 2015 09:59:05 GMT

    [ https://issues.apache.org/jira/browse/YARN-4255?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14954733#comment-14954733

Sidharta Seethana commented on YARN-4255:

[~vvasudev] , I am assuming you mean DockerLinuxContainerRuntime ? The reason for doing this
in the container-executor is that the filename has a randomly generated component. We would
have to save the filename in the NM state store (to persist across restarts) in order to clean
this up effectively in java code. A similar pattern of cleaning up command files is already
in place in container-executor (traffic shaping/tc command files are cleaned up in container-executor
as well).

These need to be cleaned up.
