Hi Ted

I declared Listclass as
public static List<Listclass> map_list_main=new ArrayList<Listclass>();

i know my logic is correct .only issue is adding my result to this
Listclass.Also my conversion works perfectly .i checked  this based on
print out put results.

only issue is why final element of Listclass updated for all elements in
list

I am using hbase version hbase-0.98.6.1
Hadoop -2.5.1

Also i using finagle client ,server module.So can u advise  How do i debug
this?

Thanks
Beeshma
