Subject [jira] [Commented] (TEZ-1233) Allow configuration of framework parameters per vertex
Date Thu, 05 Feb 2015 01:17:35 GMT

    [ https://issues.apache.org/jira/browse/TEZ-1233?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14306370#comment-14306370

Hitesh Shah commented on TEZ-1233:
----------------------------------

bq. One way I think of is adding annotation to each property

Would it be better to rely on prefixes instead? This will also help in creating better named
property configs. If some of the configs need to be renamed, we can make use of deprecation
to ensure existing users do not break.

> Currently, configuration properties specific in AMConfiguration are used to configure
tasks - e.g. memory configs, process tree, etc. These should be configurable at a Vertex level.
> Also, tasks end up reading these configs from the dist cache each time - would be simpler
to send over the wire as part of the TaskSpec.
