------------------------------------

             Summary: container-executor message on empty configuration file can be improved
                 Key: YARN-6169
                 URL: https://issues.apache.org/jira/browse/YARN-6169
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: Miklos Szegedi
            Priority: Trivial


If the configuration file is empty, we get the following error message:
{{Invalid configuration provided in /root/etc/hadoop/container-executor.cfg}}
This is does not provide enough details to figure out what is the issue at the first glance. We should use something like 'Empty configuration file provided...'
{code}
  if (cfg->size == 0) {
    fprintf(ERRORFILE, "Invalid configuration provided in %s\n", file_name);
    exit(INVALID_CONFIG_FILE);
  }
{code}
