Hi myn,
as far as I know there are not a lot of time series analyzing algorithms implemented in mahout.

To be concrete:

There are no ARIMA algorithms for forecasting:
(you could use R:

There is no fast fourier transformation:
(you could use R too:
(you could use Apache math commons:

Actually there are hidden markov models:
