> I want to process image by HIPI on Spark.So i use hadoopfile to creat RDD.
> There are my Code.
> val conf = new SparkConf().setAppName("BundleTest")
> val sc = new SparkContext(conf)
> val bundle0 = sc.hadoopFile[HipiImageHeader,HipiImage,HibInputFormat]("hdfs://192.168.199.11:8020/Hdfs/Image/image.hib.dat",1000)
> But I got an error:type arguments.
> Error:(39, 22) type arguments [org.hipi.image.HipiImageHeader,org.hipi.image.HipiImage,org.hipi.imagebundle.mapreduce.HibInputFormat] conform to the bounds of none of the overloaded alternatives of
