-------------------------------------

Hi David, 
I just tried to applied your patch, and found some issues here.

1.  Checkstyle error,  there are some CS complains about the ASF header and some package import errors. 
     It's not a big deal.
2.  It looks like the hadoop core is require JDK 1.6, so you had to tell maven compile plugin to compile the source with 1.6.
     I try to remove the that configure and got this error.
    {code}
        /Users/jiangning/Work/camel/trunk/components/camel-hdfs/src/main/java/org/apache/camel/component/hdfs/HdfsWritableFactories.java:[23,20] package javax.xml.ws does not exist

       /Users/jiangning/Work/camel/trunk/components/camel-hdfs/src/main/java/org/apache/camel/component/hdfs/HdfsConsumer.java:[25,-1] cannot access org.apache.hadoop.fs.FileStatus
bad class file: /Users/jiangning/.m2/repository/org/apache/mahout/hadoop/hadoop-core/0.20.1/hadoop-core-0.20.1.jar(org/apache/hadoop/fs/FileStatus.class)
class file has wrong version 50.0, should be 49.0

    {code}
     It will cause some trouble if we put it into Camel trunk, as we still use JDK 1.5.x for our daily build.

Before we figure out how do resolve issue 2, I can't submit your patch into Camel trunk :(
