Hi, I also had this query that might be similar to shweta.
What I want to do is process the key value pairs that I get from getTopKey() and getTopValue() methods and I want to output that value. Currently I was writing these values to tables from inside the iterators, but I read in the new manual that says that doing this isn't a good practice. For eg: If I have these entries in my table: 1 cf1:cq1 value1 2 cf2:cq2 value2 3 cf3:cq3 value3 And suppose I sum the values(or do any opeation) of the row ids using the values that I get from the getTopKey().getRow() function and store this sum in a variable called "sum". So I want to output this variable. How do I go about this? Thanks Vaibhav On 17-Apr-2015 6:40 pm, <dlmar...@comcast.net> wrote: > via the getTopKey() and getTopValue() methods.
