Subject [jira] Updated: (MAPREDUCE-905) Add Eclipse launch tasks for MapReduce
Date Fri, 18 Sep 2009 14:17:16 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-905?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Tom White updated MAPREDUCE-905:
--------------------------------

       Resolution: Fixed
    Fix Version/s: 0.21.0
         Assignee: Philip Zeyliger
     Hadoop Flags: [Reviewed]
           Status: Resolved  (was: Patch Available)

I've just committed this. Thanks Philip!

I manually tested this (the failed test from Hudson was unrelated) by using a launch to run
some unit tests. I also added .launches to svn:ignore.

> This is a revival of HADOOP-5911, but only for the MR project.
> Eclipse has a notion of "run configuration", which encapsulates what's needed to run
or debug an application. I use this quite a bit to start various Hadoop daemons in debug mode,
with breakpoints set, to inspect state and what not.
> This is simply configuration, so no tests are provided.  After running "ant eclipse-files"
and refreshing your project, you should see entries in the "Run" pulldown.  There's a template
for testing a specific test, and also templates to run all the tests, the job tracker, and
a task tracker.  It's likely that some parameters need to be further tweaked to have the same
behavior as "ant test", but for most tests, this works.
