[jira] [Updated] (YARN-7286) Add support for docker to have no capabilities

["Eric Badger (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/YARN-7286?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Eric Badger updated YARN-7286:
------------------------------
    Attachment: YARN-7286.001.patch

Attaching patch that utilizes the keyword "none" to remove force no capabilities to be added. This keyword supersedes anything else in the capabilities list. I was going to have it throw an error on a list with the "none" keyword and with extra capabilities, but the function doesn't expect an exception and I didn't want to change a bunch of function signatures. However, if that is best I can update the patch to do so.

> Support for controlling capabilities was introduced in YARN-4258. However, it does not allow for the capabilities list to be NULL, since {{getStrings()}} will treat an empty value the same as it treats an unset property. So, a NULL list will actually give the default capabilities list.
