> The kmeans algorithm fails when forced to singlenode with the following
> exception:
> {code}
> Caused by: org.apache.sysml.runtime.DMLRuntimeException: Invalid values for
> matrix indexing: dimensions of the source matrix [451x10] do not match the
> shape of the matrix specified by indices [1:10, 1:10].

> {code}
> Furthermore, there seems to be an issue of unnecessary spark context creation
> - in hybrid_spark mode we do not instantiate the spark context, while in
> forced singlenode we do.
