Arun Suresh commented on YARN-4650:
-----------------------------------
[~templedf], looks like this would be related to YARN-4083. While this seeks to
provide different set of configs (from the NM) to the AM, YARN-4083 is more
interested in the scheduler address.
I believe [~subru]/[~kishorch] had proposed to replace the HADOOP_CONF_DIR with
a HADOOP_CLIENT_CONF_DIR with different set of *-site files before launching
the AM (v9 patch of YARN-2884)
> The AM should be launched with its own set of configs instead of using the
> NM's configs

> There are cases, such as a secure LDAP configuration where the NM may need
> access to credentials that should not be exposed to the user. As long as the
> NM and AM share the same configuration files, anything exposed to the NM is
> also exposed to the AM and hence the users.
