Subject [jira] [Commented] (YARN-9053) Support set environment variables for Docker Containers In nonEntryPoint mode
Date Thu, 29 Nov 2018 02:03:00 GMT

Charo Zhang commented on YARN-9053:
-----------------------------------

[~eyang] I got it, thanks. Global environment consistency is important to me, not only we
have such usage scenarios, but also we don't want to change user habit of Docker in our Yarn
cluster. This bug was submitted to us by our platform user who knows a little Docker.

> In yarn 3.1.1, users can only set environment variables with "-shell_env" in ENTRYPOINT
mode, and variables must be registered in yarn.nodemanager.env-whitelist.
> But in nonEntryPoint mode, we should allow users to set environment variables like "-e
KEY=VAULE" in docker run command, too.
