Hello,
My name is Wei. I am trying to get started with Giraph. I am new to both Hadoop and Giraph. I have followed the "Quick Start" at http://giraph.apache.org/quick_start.html and I am able to run the SimpleShortestPathsComputation test. I intend to understand more about the code by running some examples and observing the callstack etc. I was trying to use JDB to start Hadoop with Giraph's SimpleShortestPathsComputation and set up a break point at the compute() method in SimpleShortestPathsComputation. However, the job is finished (with the correct result produced) without the breakpoint being triggered. I have two questions: (1) Could someone share some experience of using JDB to observe Giraph run ? (2) More generally, is there some recommended way to develop/debug Giraph code ? I managed to find one thread in the developer's mailing list : http://mail-archives.apache.org/mod_mbox/giraph-dev/201210.mbox/browser, titled "what is the recommended way to develop Giraph code with Eclipse or other IDEs". But I wasn't able to find any follow up information. Any input/pointer is greatly appreciated! Thanks, Wei
