java error

Hello,

 

As per my earlier mails I could not deploy Nutch on Linux . Now am
attempting the same using cygwin as per the tutorial by Peter Wang. Can
someone from the list help me resolve the attached error? Atleast on Linux I
could run the crawl.

P.S. Have sent this mail to nutch-users as well but so far no response from
their end. Am a writer and not very technical to debug the errors.

Regards,

Jaya

In general, you will find it much harder to deploy any hadoop system under
cygwin than under linux.
