Thanks, Jake. But after typing mahout vectordump --help, I got sth like
this
11/07/08 09:14:25 ERROR vectors.VectorDumper: Exception

Usage:
[--seqFile <seqFile> --output <output> --dictionaryType
<dictionaryType>
--dictionary <dictionary> --csv --useKey --printKey
--sizeOnly]
Options
--seqFile (-s) seqFile The Sequence File containing
the
Vectors
--output (-o) output The output file. If not
specified,
dumps to the
console
--dictionaryType (-dt) dictionaryType The dictionary file
type
(text|sequencefile)
--dictionary (-d) dictionary The dictionary
file.
--csv (-c) Output the Vector as CSV.
Otherwise
it substitutes in the terms
for
vector cell
entries
--useKey (-u) If the Key is a vector, then
dump
that
instead
--printKey (-p) Print out the key as well,
delimited
by a tab (or the value if useKey
is
true)
--sizeOnly (-sz) Dump only the size of the
vector
