Subject [jira] [Commented] (YARN-1743) Decorate event transitions and the event-types with their behaviour
Date Thu, 10 Jul 2014 00:10:09 GMT

    [ https://issues.apache.org/jira/browse/YARN-1743?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14056931#comment-14056931

Jeff Zhang commented on YARN-1743:

Attach one initial patch. It may need to refine later, this patch is just to illustrate my
basic idea on generating event flow between different entities.  For each event there is a
source and dest, and use this information to generate the graph viz file. The state_machine
diagram is for describing the internal transition of one entity, while this patch is for describing
the interaction between different entities. Welcome any comments and feedback on this.

> Helps to annotate the transitions with (start-state, end-state) pair and the events with
(source, destination) pair.
> Not just readability, we may also use them to generate the event diagrams across components.
> Not a blocker for 0.23, but let's see.
