Re: knowing about the vertex id of the sender of the message.

[Haowei Liu]

Sorry to be off the topic a bit.

I made my own message structure but was wondering if the received messages
are sorted based on sender id?

I am not able to verify since the call Log.debug() doesn't seem to print
out anything.

Thanks,

 Hi Jyoti,

 You can simply make the sender id a part of the message.

 Best,

question about logging

[Haowei Liu]

Hi,

 I am fairly new to apache hadoop related technologies. I was wondering
how I can enable to logging to print out the vertex values at each step for
debugging purpose. For instance, when I play around the shortestpath
example, the log.debug function doesn't seem doing anything.

 Any suggestions?

Thanks,
