Hi Jyoti,

You can take a look inside of org.apache.giraph.aggregators package, there are many implementations
already there. Some simple, like LongSumAggregator, and some more complex ones inside of matrix
package. Please look through that and let me know if you need additional help.
When you manage to implement this, you can also contribute it back to Giraph!

Subject: About writing our own aggregator..

Hi Folks...
I am trying to implement one graph algorithm on giraph.
I want that all vertices send their ids to the master .For that I need to implement my own
aggregator class.
Please suggest me how to proceed...
