Subject [jira] [Created] (YARN-814) Difficult to diagnose a failed container launch when error due to invalid environment variable

Hitesh Shah created YARN-814:
--------------------------------

             Summary: Difficult to diagnose a failed container launch when error due to invalid
environment variable
                 Key: YARN-814
                 URL: https://issues.apache.org/jira/browse/YARN-814
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Hitesh Shah


The container's launch script sets up environment variables, symlinks etc. 

If there is any failure when setting up the basic context ( before the actual user's process
is launched ), nothing is captured by the NM. This makes it impossible to diagnose the reason
for the failure. 

To reproduce, set an env var where the value contains characters that throw syntax errors
in bash.
