Class Summary

Class	Description
AffinityMatrixInputJob
AffinityMatrixInputMapper	Handles reading the files representing the affinity matrix.
AffinityMatrixInputReducer	Tasked with taking each DistributedRowMatrix entry and collecting them into vectors corresponding to rows.
IntDoublePairWritable	This class is a Writable implementation of the mahout.common.Pair generic class.
Keys
MatrixDiagonalizeJob	Given a matrix, this job returns a vector whose i_th element is the sum of all the elements in the i_th row of the original matrix.
MatrixDiagonalizeJob.MatrixDiagonalizeMapper
MatrixDiagonalizeJob.MatrixDiagonalizeReducer
UnitVectorizerJob	Given a DistributedRowMatrix, this job normalizes each row to unit vector length.
UnitVectorizerJob.UnitVectorizerMapper
VectorCache	This class handles reading and writing vectors to the Hadoop distributed cache.
VectorMatrixMultiplicationJob	This class handles the three-way multiplication of the digonal matrix and the Markov transition matrix inherent in the Eigencuts algorithm.
VectorMatrixMultiplicationJob.VectorMatrixMultiplicationMapper
VertexWritable	Represents a vertex within the affinity graph for Eigencuts.
