Re: Extending AbstractComputation

Hi Pushparaj and Peter, There is going to be one Computation per partition in each of the supersteps. Each partition is processed by a single thread, so accessing any data inside of your Computation is thread-safe. Multiple threads are going to be executing computation on multiple partitions, a

Re: A Vertex Holds Other Than Text

Hi Agrta, Take a look at IntIntTextVertexValueInputFormat for example, where vertex values are ints. If your vertex values are complex objects, you need to create a class which implements Writable interface which is going to hold all your data, and then extend the input format to read all the d

Re: Tracking Bytes Sent

Hi Young, You can set giraph.metrics.enable to true, and then in worker logs (stderr part) you'll see more information about each superstep. What you are interested in will be shown in requests-sent and sent-bytes, there is an equivalent for received as well. Regards, Maja From: Young Han ma
