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:

and then make sure you are reusing HBaseConfiguration as often as you can.

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
