Andy Seaborne commented on JENA-1522:
-------------------------------------
Brian - How are you running Fuseki?
The supplied script "fuseki" should write to the logs area. I don't think
docker makes any difference other than the fact the output is to the docker
mapped filesystem.
If you run the WAR file, it will be in catalina.out because the core engine
defaults to logging to stdout. (If there is a log4j.properties file in the
directory where Fuseki starts, this is read and respected.)

> Key: JENA-1522
> URL: https://issues.apache.org/jira/browse/JENA-1522
> Project: Apache Jena
> Issue Type: Bug
> Components: Fuseki, Jena
> Affects Versions: Jena 3.6.0
> Environment: System 1: Centos 7, Jena 3.6, Unknown Fuseki version.
> System 2: Ubuntu 16.04 running Docker. Running stain/jena-fuseki from the
> official Docker Hub.

> Reporter: Brian Mullen
> Priority: Critical
>
> In my 500M+ triple dataset, queries seem to be failing for no clear reason.
> Here's an example.
> {code:java}
> prefix Products: <http://www.example.com/test/Products#>
> select ?p ?o
> where {
> Products:ABC ?p ?o .
> }
> {code}
> ...results in a list like:
> {code:java}
> Products:HasComponent Products:DEF
> Products:HasComponent Products:GHI {code}
> Now running this query:
> {code:java}
> prefix Products: <http://www.example.com/test/Products#>
> select ?p
> where {
> Products:ABC ?p Products:DEF .
> } {code}
> ...has no results. How is this possible?
>
> Here's another example.
> {code:java}
> prefix Products: <http://www.example.com/test/Products#>
> ask where {
> Products:ABC Products:PartNumber ?p .
> filter ( ?p = "ABC" )
> } {code}
> This returns "True"
>
> {code:java}
> prefix Products: <http://www.example.com/test/Products#>
> ask where {
> ?s Products:PartNumber ?p .
> filter ( ?p = "ABC" )
> } {code}
> This returns "False"
>
> What other info can I provide?
