> I am using the Distributed Lanczos solver which uses the DistributedRowMatrix
> class for it's internal calculation. In our environment, I need to set some
> Configuration properties (specifically hadoop.job.ugi & hadoop.queue.name),
> which are when set via the setConf() method on DistributedLanczosSolver.
> These are correctly passed to DistributedRowMatrix via its setConf() method,
> but are not passed into the Hadoop JobConfs created by the various static
> routines in MatrixMultiplicationJob, TimesSquaredJob, and TransposeJob.
