Constructor Detail

GraphJob

public GraphJob(HamaConfiguration conf,
        Class<?> exampleClass)
         throws IOException

Creates a new Graph Job with the given configuration and an exampleClass. The exampleClass is used to determine the user's jar to distribute in the cluster. This constructor sets the vertex id class to Text, the vertex value class to IntWritable and the edge value class to IntWritable.

Throws:

IOException
