thanks Lewis.
I am sorry but i have to bother you with this. could tell me how I can
have nutch ant fetch the 0.90.6 instead of 0.90.4 because, according to
ant report, it is being fetch indirectly by gora 0.2.1. I am actually
using 0.90.6 for my hbase, but I don't how modify ivy.xml file to
accomplish that.
thanks,

Has anyone encounter this error before:

what configuration in zookeeper is it talking about?
for the record, I think, this is the error in the zookeeper log file that
it is talking about ( it is the only error in my log file):

I am also concern about this happening on the loop back interface. doesn't
look right to me.
oh and btw this is on hadoop cluster with 10 nodes
