Matthew Sharp commented on YARN-10493:
--------------------------------------
I looked at YARN-10494 (CLI Tool) design and that was the missing piece. I
originally included a static directory you can set for a single namespace
(defaults to library if you don't). But the CLI tool design pdf and your usage
example makes more sense, to make that user configurable and only default to a
namespace if that is not provided. I can work on an update to support that and
also add to the pdf design to make that more clear.
YARN_CONTAINER_RUNTIME_RUNC_IMAGE=[namespace]/<image>[:tag]
Examples:
{code:java}
YARN_CONTAINER_RUNTIME_RUNC_IMAGE=busybox
/runc-root/meta/library/busybox@latest.properties{code}
{code:java}
YARN_CONTAINER_RUNTIME_RUNC_IMAGE=hadoop/busybox:latest
/runc-root/meta/hadoop/busybox@latest.properties
{code}
{code:java}
YARN_CONTAINER_RUNTIME_RUNC_IMAGE=shared/busybox:1.0.0
/runc-root/meta/shared/busybox@1.0.0.properties
{code}
