Hadoop now has a <a href="http://wiki.apache.org/lucene-hadoop/FAQ">FAQ</a>. Please help make this more complete!

|
-<h3 class="h4"> 5 May, 2006: release 0.2.0 available </h3>
|
|
|
-<p>
|
|
|
- We are now aiming for monthly releases. There have been many bug fixes and improvements in the past month.
|
|
|
- MapReduce and DFS are now fairly reliable on clusters with up to 200 nodes.

-<h3 class="h4"> 6 February, 2006: nightly builds </h3>
|
|
|
-<p>
|
|
|
- Hadoop now has nightly builds. This automatically creates a <a href="http://lucene.zones.apache.org:8080/hudson/job/Hadoop-Nightly/">downloadable version of Hadoop every night</a>.
|
|
|
- All unit tests must pass, or a message is sent to the developers mailing list and no new version is created.
|
|
|
- This also updates the <a href="http://lucene.apache.org/hadoop/api/index.html">javadoc</a>.

|
|
|
-<p>
|
|
|
- The Hadoop code has now been moved into its own Subversion tree, renamed into packages under org.apache.hadoop.
|
|
|
- All unit tests pass, but little else has yet been tested.
