> Key: YARN-10355
> URL: https://issues.apache.org/jira/browse/YARN-10355
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: yarn
> Reporter: Benjamin Teke
> Assignee: Tamas Domok
> Priority: Minor
>
> The {{org.apache.hadoop.yarn.server.nodemanager.containermanager.launcher.ContainerLaunch#orderEnvByDependencies}} and it's helper method \{{getEnvDependencies }}(together with the overrides) is hard to read. Some improvements could be made:
> * use Pattern matching in the overrides of getEnvDependencies instead of iterating through the environmental variable strings char by char
> * the unit tests contains a lot of repeated code and generally the test methods are long - they could be separated into different setup/helper and assertion methods
