      Description

      The following code in MultithreadedMapRunner.java does not get published to the HTML docs correctly.

      This is what actually appears in the HTML docs:
      "It can be used instead of the default implementation, "

      This is what should appear:
      /**

      • Multithreaded implementation for @link org.apache.hadoop.mapred.MapRunnable.
      • <p>
      • It can be used instead of the default implementation,
      • @link org.apache.hadoop.mapred.MapRunner, when the Map operation is not CPU
      • bound in order to improve throughput.
      • <p>
      • Map implementations using this MapRunnable must be thread-safe.
      • <p>
      • The Map-Reduce job has to be configured to use this MapRunnable class (using
      • the JobConf.setMapRunnerClass method) and
      • the number of thread the thread-pool can use with the
      • <code>mapred.map.multithreadedrunner.threads</code> property, its default
      • value is 10 threads.
      • <p>
