The Mahout 0.11.0 Shell requires Spark 1.3. Please try with Spark 1.3.1.

I tried Spark 1.4.1, same error. Then I saw the same error from shell command.
So I suspect that it is the environment configuration problem.
I have followed this https://mahout.apache.org/general/downloads.html for
Mahout configuration.
So it seems to be a Spark configuration problem, I guess,
Totally an approximation; depends on why people are asking for the inverse
and whether it'd do.

Go, if you'd like to put your research team in touch with the list we may
be able to help work through a good approach; let us know.

Mahout translation (approximation, since ssvd is reduced-rank, not the true
thing):
val (drmU, drmV, s) = dssvd(drmA, k = 100)
val drmInvA = drmV %*% diagv(1 /=: s) %*% drmU.t
Still, technically, it is a right inverse as in reality m is rarely the
same as n. Also, k must be k<= drmA.nrow min drmA
Yeah, nice trick Ted; here's a how-to for the list:

Can you share the actual mathematical specification for your problem?
If you can't, then there is little we can do to help.
