Hello guys, I am trying to run the SimpleShortestPathComputation and SimplePageRankComputation by running the command on Giraph Quick start site.
I do understand the command: it specifies the vertex input format as JsonLongDoubleFloatDoubleVertexInputFormat, vertex input path as /user/hduser/input/tiny_graph.txt, vertex output format is IdWithValueTextOutputFormat and it also specifies the output path. But I do not get any output after running although the code runs fine and no errors occurred. The input format is copy from the site and paste into a text file. Please take a look at the attachment for the log file in xml format found in Hadoop output path. I am pretty new to Giraph so I do need a running example to see exactly what's happening. Also I have a question: is this example project directly from Giraph community? Link: https://apache.googlesource.com/giraph/+/old-move-to-tlp/src/main/java/org/apache/giraph/examples/ I tried to compile the file SimpleShortestPathsVertex.java and I got many errors: such as import org.apche.giraph.lib.*; lib class is not found. Many thank and I look forward to hearing from you soon.
