Dear developers,
In order to run a benchmark on apache-rya database technology I have
installed rya-incubating
3.2.10 on a cluster.
When I try to run the following query:
select ?s ?p ?o
>
> where {
>
> ?s ?p ?o .
>
> }
In response I have a http status 500 - internal server error:

Is this a limitation of the technology or I can avoid this issue someway?
I look forward to hearing from you.
