Subject [jira] [Commented] (TEZ-345) Command line -D parameters no longer respected in the AM
Date Tue, 06 Aug 2013 23:13:48 GMT

    [ https://issues.apache.org/jira/browse/TEZ-345?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13731425#comment-13731425
] 

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

Are we expecting the client to specify YARN configuration parameters (like RM address), or
is the AM supposed to always pick it up from the deployed yarn-site.xml ?
Earlier, the client would specify this. Currently, it looks like yarn-site in the classpath
is the source.

> -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.
