Subject [jira] [Commented] (TEZ-345) Command line -D parameters no longer respected in the AM
Date Tue, 06 Aug 2013 06:32:54 GMT

    [ https://issues.apache.org/jira/browse/TEZ-345?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13730433#comment-13730433

Siddharth Seth commented on TEZ-345:
------------------------------------

This really depends on where we're going with the AM. Will it run a single DAG at a time,
or can it run multiple DAGs concurrently. Scheduling configuration should likely be DAG specific.
IAC, DAG configuration vs AM configuration is a useful distinction to have. As is, separating
AM configuration from Client configuration and Runtime configuration.

> -D parameters specified at command line are no longer used in the AM (likely broken after
TEZ-323) - specifically scheduler options like heartbeat time, reuse etc. This would have
to be reconsiled with TEZ-340, TEZ-341 which would allow multiple DAGs to be submitted via
a single AM.
