> Key: YARN-813
> URL: https://issues.apache.org/jira/browse/YARN-813
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: nodemanager
> Affects Versions: 2.0.4-alpha, 0.23.8
> Reporter: Hitesh Shah
>
> What should a user of yarn escape/not escape when passing in input for the
> container launch contexts
> - localized resources' names are used to create symlinks.
> - Are special chars supported in symlinks or do they need to be escaped?
> - Likewise for environment variables and commands.
> Current implementation uses a shell script to setup the environment and
> launch the commands. What should the user be aware of when setting up the
> launch context? The input also should be such that a user should not need to
> change code based on what platform or flavor of shell is being used to setup
> the env and run the commands.
