Subject [jira] [Updated] (YARN-7224) Support GPU isolation for docker container
Date Tue, 10 Oct 2017 23:52:00 GMT

     [ https://issues.apache.org/jira/browse/YARN-7224?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Wangda Tan updated YARN-7224:
    Attachment: YARN-7224.003.patch

Attached ver.003 patch, major updates:

1) Instead of using {{volume-driver}}, this patch added {{docker volume create}} command to
c-e and NM Java side. The reason is {{volume-driver}} can only use single volume driver for
each launched docker container.

2) Updated {{c-e}} and Java side, if a mounted volume is a named volume in docker, skip checking
file existence. (Named-volume still need to be added to permitted list of container-executor.cfg).

3) More tests and cleanups.

We need to add support to help docker containers launched by YARN can utilize GPUs.
