Alejandro Abdelnur commented on YARN-2429:
------------------------------------------
Unless I'm mistaken, the blacklisting is done in the C code. Currently Hadoop
uses the {{Groups}} class to fetch group info, there are multiple plugins for
it (shell, ldap, jni, ...). This means that you'd have to either get all groups
of the user before calling the LCE and passing them as params, or the LCE would
have to connect to the same group source as the Java side of things.
> LCE should blacklist based upon group
