Subject [jira] Created: (HADOOP-602) Remove Lucene dependency
Date Fri, 13 Oct 2006 10:30:38 GMT
Remove Lucene dependency
------------------------

                 Key: HADOOP-602
                 URL: http://issues.apache.org/jira/browse/HADOOP-602
             Project: Hadoop
          Issue Type: Improvement
    Affects Versions: 0.8.0
            Reporter: Andrzej Bialecki 
         Assigned To: Andrzej Bialecki 
             Fix For: 0.8.0


Hadoop uses just a single class from Lucene, namely the PriorityQueue. I propose to remove
this dependency by copying this class into org.apache.hadoop.util.PriorityQueue and removing
lucene-core.jar from dependencies.

Removing this dependency makes it easier to run map-reduce applications that use different
versions of Lucene.
