val rows = IndexedRow(0L, new DenseVector(Array(1,2,3))) :: IndexedRow(1L, new DenseVector(Array(1,2,3))):: IndexedRow(2L, new DenseVector(Array(1,2,3))):: Nil
val rdd = sc.parallelize(rows)

val imat = bmat.toIndexedRowMatrix
imat.rows.collect // this throws an error - Caused by: java.lang.IllegalArgumentException: requirement failed: Vectors must be the same length!
