> The configuration of "yarn.nodemanager.env-whitelist" has been helpful in
> running multi version Hadoop on Yarn. But the pain point is that users need
> to use different configurations to run jobs of different versions of Hadoop.
> The first idea is to have SRE prepared different versions of configurations
> and let users specify different environment variables of "HADOOP_CONF_DIR",
> this shifts the burden from users to SRE that they have to maintain different
> versions of configurations with only one or two configurations changed.
> This ticket proposes to export the value of the environment variable in
> "yarn.nodemanager.env-whitelist" via the environment variable or Java
> properties of the client submitting jobs. So that SRE only has to maintain
> one version of configuration and users can easily define Hadoop version with
> one export in an environment variable or Java property.
