OWLAPI failing in Hadoop environment #697

Closed nickrobison closed 7 years ago

nickrobison commented 7 years ago

I've run into an issue running some of our code in a Hadoop environment. While everything runs nicely in our current environments, when we attempt to execute with Hadoop we run into the following error:

org.semanticweb.owlapi.io.UnparsableOntologyException: Problem parsing inputstream:ontology3678919686534481
Could not parse ontology.  Either a suitable parser could not be found, or parsing failed.  See parser logs below for explanation.
The following parsers were tried:
1) org.semanticweb.owlapi.oboformat.OBOFormatOWLAPIParser@3523a08a

The ontology we're attempting to load is an OWLXML file, located on a shared server accessible to the worker machines. It seems like the OWLAPI is only trying the OBO parser and none of the other parsers in the classpath.

As we distribute the application as an uber jar, I can verify that the required classes (owlapi-parsers, owlapi-rio packages) are indeed loaded on the classpath.

Any insights would be greatly appreciated.

What do the META-INF/services files inside of the uber jar look like?

I should probably also clarify that I'm using OWLAPI 5.1.1.

nickrobison commented 7 years ago

Your comment pointed me in the right direction, the OWLParserFactory in the services/ directory was only listing the OBO parser. Turns out I had a missing resource transformer, which was causing the other entries to be removed. Adding that solved the issue!

ansell commented 7 years ago

They are probably okay, but double-check that there is more than one line in the following: 

META-INF/services/org.semanticweb.owlapi.io.OWLParserFactory
META-INF/services/org.eclipse.rdf4j.rio.RDFParserFactory
META-INF/services/org.semanticweb.owlapi.model.OWLDocumentFormatFactory

If they only contain one line or are less than expected, then you may need to adjust the merge method so that it concatenates the META-INF/services files together rather than selecting the first/last one and discarding the others.

https://maven.apache.org/plugins/maven-shade-plugin/examples/resource-transformers.html#ServicesResourceTransformer

https://maven.apache.org/plugins/maven-assembly-plugin/examples/single/using-container-descriptor-handlers.html

Also interesting that there is the following file, but may be necessary for the other libraries so probably not an issue overall:

META-INF/services/org.openrdf.rio.RDFParserFactory

Sorry, comments overlapped!

nickrobison commented 7 years ago

No problem, thanks for the quick response!

ignazio1977 commented 7 years ago

Faster than me thanks to time zones :-) similar issues have been seen in the past due to different aggregation techniques used to create uber jars by other developers, the problem is as you've found - if the aggregation transforms do not create the right files in the meta-inf/services folder, only a subset of parsers is created.

There is a unit test that checks that the number of parsers is as expected, maybe it could be moulded into an integration test for your uber parser generation process. See https://github.com/owlcs/owlapi/blob/version5/contract/src/test/java/org/semanticweb/owlapi/rio/OWLOntologyStorerFactoryRegistryTestCase.java
