Mahout does not have an implementation of pLSI. We have two examples for
a recommender that uses a parallel matrix factorization via Alternating
Least Squares:
examples/bin/factorize-movielens-1M.sh
examples/bin/factorize-netflix.sh

Ziad,
you can look at SSVD/PCA doc on mahout wiki. It has an overview
section, which is not technically tutorial per se, but gives you
necessary background to use PCA/dimensionality reduction and LSA
fold-in/ similarity measure techniques. (well, perhaps not
similarities, not there).
PCA/Dimensionality reduction also just one step and is fully
supported by this single step assuming you have your data prepped
row-wise. I am not sure that there's much of tutorial to be had there,
again, it's one step as explained there. SVD-based LSA (and especially
LSI) is a somewhat more involved topic, but then again you can use
df/itf pipeline ( seq2sparse, etc) as defined in the book and then run
SSVD on the results to get desired LSA space. One detail that is often
desired for LSA fold-ins and which may not be (i am not sure)
described in sufficient detail in the book is the dictionary structure
(which probably still will have to be re-indexed in some more suitable
real-time format anyway).
SVD LSA is quite not the same as pLSA though (and i am not even sure
if Mahout supports pLSA pipeline. Mahout LDA is considered to be the
most successful push in that direction though.)

Some examples with new recommendations like pLSA, matrix factorization and PCA
