> container-executor: misc improvements in child processes and exec() calls
> -------------------------------------------------------------------------
>
> Key: YARN-10019
> URL: https://issues.apache.org/jira/browse/YARN-10019
> Project: Hadoop YARN
> Issue Type: Bug
> Components: nodemanager
> Reporter: Peter Bacsko
> Assignee: Peter Bacsko
> Priority: Major
> Attachments: YARN-10019-001.patch
>
>
> There are a couple of improvements that we can do in container-executor
> regarding how we exit from child processes and how we handle failed exec()
> calls:
> 1. If we're in the child code path and we detect an erroneous condition, the
> usual way is just simply call {{_exit()}}. Normal {{exit()}} occurs in the
> parent. Calling {{_exit()}} prevents flushing stdio buffers twice and any
> cleanup logic registered with {{atexit()}} or {{on_exit()}} will run only
> once.
> 2. There's code like {{if (execlp(script_file_dest, script_file_dest, NULL)
> != 0) ...}} which is not necessary. Exec functions are not supposed to
> return. If they do, it's definitely an error, so no need to check the return
> value.
