      Description

      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.
