Usage:
[--input <input> --output <output> --useKey <useKey> --printKey <printKey>
--dictionary <dictionary> --dictionaryType <dictionaryType> --csv <csv>
--namesAsComments <namesAsComments> --nameOnly <nameOnly> --sortVectors
<sortVectors> --quiet <quiet> --sizeOnly <sizeOnly> --numItems <numItems>
--vectorSize <vectorSize> --filter <filter1> [<filter2> ...] --help --tempDir
<tempDir> --startPhase <startPhase> --endPhase <endPhase>]
Job-Specific Options:
--input (-i) input Path to job input directory.
--output (-o) output The directory pathname for output.
--useKey (-u) useKey If the Key is a vector than dump
that instead
--printKey (-p) printKey Print out the key as well,
delimited by tab (or the value if
useKey is true
--dictionary (-d) dictionary The dictionary file.
--dictionaryType (-dt) dictionaryType The dictionary file type
(text|seqfile)
--csv (-c) csv Output the Vector as CSV.
Otherwise it substitutes in the
terms for vector cell entries
--namesAsComments (-n) namesAsComments If using CSV output, optionally add
a comment line for each NamedVector
(if the vector is one) printing out
the name
--nameOnly (-N) nameOnly Use the name as the value for each
NamedVector (skip other vectors)
--sortVectors (-sort) sortVectors Sort output key/value pairs of the
vector entries in abs magnitude
descending order
--quiet (-q) quiet Print only file contents
--sizeOnly (-sz) sizeOnly Dump only the size of the vector
--numItems (-ni) numItems Output at most <n> vecors
--vectorSize (-vs) vectorSize Truncate vectors to <vs> length
when dumping (most useful when in
conjunction with -sort
--filter (-fi) filter [filter ...] Only dump out those vectors whose
name matches the filter. Multiple
items may be specified by repeating
the argument.
--help (-h) Print out help
--tempDir tempDir Intermediate output directory
--startPhase startPhase First phase to run
--endPhase endPhase Last phase to run
