Subject [jira] [Updated] (YARN-7286) Add support for docker to have no capabilities
Date Mon, 16 Oct 2017 13:43:01 GMT

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

Eric Badger updated YARN-7286:
------------------------------
    Attachment: YARN-7286.005.patch

bq.  I see negative/failure tests in 'testDockerCapabilities' ; do you mind adding a test
to ensure that using just "none" (or "NONE") leads to an empty capability list on container
launch?
Thanks for pointing this out, [~sidharta-s]! Attaching a new patch that adds test cases for
"none" and "NONE".

> 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.
