Subject [jira] [Commented] (YARN-3033) implement NM starting the ATS writer companion
Date Fri, 06 Feb 2015 18:28:35 GMT

    [ https://issues.apache.org/jira/browse/YARN-3033?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14309574#comment-14309574

Sangjin Lee commented on YARN-3033:
-----------------------------------

[~djp], I think it'd be good to support *both* options.

I do see some may want to run it as an aux service for simplicity of deployments (one fewer
daemons to start), especially in a small setup. However, we do need to address the web app
issue at YARN-3087 to avoid the undesirable module dependency.

A standalone is probably safer as it would affect the node manager less. We still need to
poke this daemon for the AM lifecycle (thus the service part).
