Subject [jira] [Commented] (YARN-4650) The AM should be launched with its own set of configs instead of using the NM's configs
Date Thu, 28 Jan 2016 18:07:39 GMT

    [ https://issues.apache.org/jira/browse/YARN-4650?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15122000#comment-15122000

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)

> 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.
