Hi All, This issue came up on several occasions. Since people seem to agree on using "#pragma once" instead of "#define" guards that we have using, I wanted to send a quick email to gather some consensus around it. If everyone agrees about the switch, we can update the style guide and start using "#pragma once".
The issue is tracked at https://issues.apache.org/jira/browse/MESOS-2211 and there is a review request at https://reviews.apache.org/r/30100/. Please note that this won't be a mass update. We should keep updating the files that are created/updated (similar in spirit to "> >" to ">>" change). If there are any concerns, please let us know. We would very much like to commit this by tomorrow and any feedback before that is highly appreciated. Best, Kapil
