Subject [jira] [Commented] (YARN-378) ApplicationMaster retry times should be set by Client
Date Thu, 14 Mar 2013 17:40:13 GMT

    [ https://issues.apache.org/jira/browse/YARN-378?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13602481#comment-13602481

Bikas Saha commented on YARN-378:
---------------------------------

env vars are brittle from an api point of view. windows supports such use cases fine. the
point being for a application developers the information should come from the api, and not
from a combination of api and env. env requires an agent on the other side to set the env
apart from the info coming from the api itself. here is works because the agent on the other
side happens to be the NM which is in our control.
To summarize, lets agree to keep this in the API as it exists in the patch. For the MR AM's
sake, we could additionally add the information in the env also.

> We should support that different client or user have different ApplicationMaster retry
times. It also say that "yarn.resourcemanager.am.max-retries" should be set by client.
