> buildCommandExecutor function leverages redundant params
> ---------------------------------------------------------
>
> Key: YARN-11256
> URL: https://issues.apache.org/jira/browse/YARN-11256
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: yarn
> Reporter: Samrat Deb
> Assignee: Samrat Deb
> Priority: Minor
> Labels: pull-request-available
>
> Current signature of `buildCommandExecutor` passes redundant params which can
> be reduced by passing container reference
>
> {code:java}
> protected CommandExecutor buildCommandExecutor(String wrapperScriptPath,
> String containerIdStr, String user, Path pidFile, Resource resource,
> File workDir, Map<String, String> environment){code}
>
> - `containerIdStr` can be derived from
> `container.getContainerId().toString()`
> - `resource` can be derived from `container.getResource()`
> - `environment` can be derived from container reference
> this will allow extention of the function without constraining to paramters
> of the method
> Container reference is safe as it is pass by reference it wont copy the
> entire the container object
>
