Brian McBride commented on RYA-83:
----------------------------------
FWIW, when I first tried using Rya, SELECT { ?s ?p ?o } LIMIT 10 was, as usual,
my first test query. Getting back "not supported" resulted in me thinking "not
standards conformant then".
There are lots of queries that will stress a triple store. Maybe the thing to
think about is how to limit the resource consumed by an arbitrary query, rather
than syntactically recognising and blocking just one.

> Key: RYA-83
> URL: https://issues.apache.org/jira/browse/RYA-83
> Project: Rya
> Issue Type: Bug
> Environment: Accumulo 1.6.5 installed on EMR 4.6.0 (Hadoop 2.6.0)
> Reporter: Kiet Ly
>
> I ran this query using REST
> http://10.162.96.61:8000/web.rya/queryrdf?query=select * where { ?s ?p ?o }
> and it crashed. I just want to see the triples that I had inserted. I ran the
> query against the RYA I built from develop branch with accumulo 1.6.5.
> The error indicate this query is not supported, "select * where { ?s ?p ?o
> }".
