Hi Fan,
The tutorial is a bit dated, so it might be confusing/incorrect.
You have a couple options:
1. You could start using the Vagrant vm that I'm putting together as a "Rya Quickstart VM".
It's a bit rough right now, and it doesn't have Hadoop or MapReduce (so you can't do the bulk load), but it does have the script you mentioned for loading N-Triples. An early copy of the Vagrantfile is here [1].
It'll take about 30 minutes to build the VM, but once you do, you'll have the rya web endpoint up and running here [2] and you can ssh into the box to load data. Once you ssh into the machine, you can run 'java LoadDataServletRun' to load n-triples files. Infact, you that script will take a "batchSize" parameter to split a large ntriples into small loads.
2. We can help you debug your current vm.
The first step would be to try to hit this webpage [3] and see if the sparql query page loads. Also note that the URL you provided has an extra "/" in it and you should try [4].
If those load properly, then the issue might be the LoadDataServletRun file itself (I haven't tried the one you mentioned), but you could try the new one located at the bottom of the Vagrant file.
If those links do not load properly, please send us your tomcat logs and we'll take a look to see what's up with tomcat.

Hi Aaron,
Sorry to bother you again. I faced a new problem in loading RDF data process. Following the tutorial, I created loadrdf folder and N-Triples file $RDF_DATA, when I complied and run the java code, it gave the error message like :”java.io.IOException: Server returned HTTP response code: 500 for URL: http://localhost:8080/web.rya/loadrdf/?format=N-Triples” my tomcat host server’s URL is localhost and port number is 8080 by default.
Also another question is about bulk load RDF data. There is an example code in the tutorial, I’ve tried to find the similar jar package named accumulo.rya-3.0.4-SNAPSHOT-shaded.jar, unfortunately the only one I could found is accumulo.rya-3.2.10-SNAPSHOT.jar and when I replaced the code with this one, it said it’s not a valid jar.
Please let me know if I misunderstood and did anything wrong with the tutorial, thank you very much!
Bests,
Fan Hey Fan. Are you on the dev list? I didn't do a "reply-all"...
My response to your email this morning is below. Hey Fan!
Thanks for downloading Rya and testing it out.
It appears that you must use Maven 3 (for kinda a funny reason... it'll hit the apache repo by default), and it appears that there are some test issues with mvm.rya.accumulo.AccumuloRyaDAOTest.
You should be able to build rya using this command (with maven 3): mvn clean install -DskipTests
Regardless, we need to create an ticket to fix your broken test. Could you send out your test report? Specifically, we're interested in : dao/accumulo.rya/target/surefire-reports/mvm.rya.accumulo.AccumuloRyaDAOTest.txt Hi,
My name is Fan Yang, I am a phd student in Information Systems Department, UMBC. Currently I am working on Rya project under the supervision of Dr. Adina. I faced a problem when I tried to reproduce the development environment on my virtual machine.
When I built Rya project by Maven, it gave me some error report and same thing happened even I tried different versions of Maven. I am attaching the log files generated by Maven 3.3.3 (log333.txt) and Maven 2.2.1 (log221.txt) and looking for some help. Thank you so much!
My development environment is:
OS: Hortonworks Sandbox with HDP 2.2.4 (Cent OS 6 64bit)
Maven version: 3.3.3
Java version: OpenJDK Runtime Environment 1.7.0_79
Accumulo version: 1.6.1.2.2.4.2-2
Hadoop version:2.6.0.2.2.4.2-2
Bests,
Fan
