Subject [jira] [Commented] (CRUNCH-423) Add documentation on automated plan logging to User Guide
Date Wed, 18 Jun 2014 14:26:07 GMT

    [ https://issues.apache.org/jira/browse/CRUNCH-423?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14035721#comment-14035721

Allan Shoup commented on CRUNCH-423:
------------------------------------

Here's a first stab at some documentation:

Under the MRPipeline configuration options section:
||Name||Type||Usage Notes||
|crunch.planner.dotfile.outputdir|string|A file system directory URI indicating where MapReduce
pipeline plan files will be stored. If this is set, a plan file in <a href="http://www.graphviz.org">DOT</a>
format will be stored for each run of the pipeline. The format of the file name will be the
first 150 characters of the URL-encoded pipeline name, followed by an underscore, followed
by a timestamp using the <a href="http://docs.oracle.com/javase/6/docs/api/java/text/SimpleDateFormat.html">yyyy-MM-dd_HH.mm.ss.SSS
format</a>, and ending with "_jobplan.dot" (for example Pipeline%20Name_2014-06-18_09.15.32.419_jobplan.dot).
If this is not set, plan files will not be written.|

> CRUNCH-418 introduced a useful new feature that allows writing job plan dot files to
a configured output directory. Once it is in a released version of Crunch, the user guide
should be updated to document this new functionality.
