[jira] [Created] (YARN-10355) Refactor NM ContainerLaunch.java#orderEnvByDependencies

[Benjamin Teke (Jira)]

Benjamin Teke created YARN-10355:


 Summary: Refactor NM ContainerLaunch.java#orderEnvByDependencies
 Key: YARN-10355
 URL: https://issues.apache.org/jira/browse/YARN-10355
 Project: Hadoop YARN
  Issue Type: Improvement
  Components: yarn
Reporter: Benjamin Teke


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 - it could be separated into different setup/helper and 
assertion methods
