Subject [jira] [Commented] (YARN-378) ApplicationMaster retry times should be set by Client
Date Thu, 14 Mar 2013 05:46:14 GMT

    [ https://issues.apache.org/jira/browse/YARN-378?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13602055#comment-13602055

Vinod Kumar Vavilapalli commented on YARN-378:
----------------------------------------------

+1 for maxAppAttempts naming.

+1 to Bobby's proposal to add it to env. We are sending across other important things like
app-attempt-id as part of the env, so +1 for adding this info too.

bq. First in some init method that reads the global value from config, checks for errors and
sets a sensible default global value.
Yes, this should happen somewhere in the main thread and crash the RM in case of invalid configs.
RMApp gets created much later, so..

bq. Env vars are brittle..
I suppose this is on Windows?

> 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.
