Subject [jira] [Commented] (MAPREDUCE-2930) Generate state graph from the State Machine Definition
Date Wed, 21 Sep 2011 08:45:09 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2930?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13109348#comment-13109348

Vinod Kumar Vavilapalli commented on MAPREDUCE-2930:
----------------------------------------------------

bq. -1 tests included. The patch doesn't appear to include any new or modified tests.
Forgot to comment on this. This issue introduced code for generating state graphs. Cannot
put automatic test as it needs an external dependency on graphviz package. I tested this manually
anyways besides Binglin's attached graphs.

> It would be nice to automatically generate the state machine visualization from the state
machine declaration using graphviz or some such. Some state graphs already attached to MAPREDUCE-279.
