SPARQL predicate query gives TimeOutException #82

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Import the attached TTL file.
2. Use the web interface or evaluate in the SPARQL query from Java code.
3. Results in Error 400 (runned in the browser), TimeOutException (in Java code)

What is the expected output? What do you see instead?
:x4 :x5 should be returned.

What version of the product are you using? On what operating system?
CumulusRdf 1.0.1, Cassandra 2.0.8

Please provide any additional information below.

Running queries collecting nodes with the rdf:type predicate runs without 
problem.

Hi, 
CumulusRDF 1.0.1 doesn't support Cassandra 2.x. It will do in 1.1.x. I will ask 
more information to who is more expert than me about this topic but I guess 
this is part of the issue

Best, 
AG

Yes, thank you, this was the problem. After reverting to Cassandra 1.2.16 it 
works.

Thank you again,
Daniel
