Error when loading a bulk .zip containing database #43

Open gatemezing opened 7 years ago

gatemezing commented 7 years ago

Hi, I am trying to use Blazegraph to load a .zip database triples of over 4GB on disk. I am on windows and this is the error I get: No parser factory for available for RDF format null. Is it that .zip compressed files are not accepted by the loader? I am using the command: java -cp blazegraph.jar com.bigdata.rdf.store.DataLoader myfile.properties d:\path\to\dataset\name.zip

If you name the file such that the extension can be guessed, it will work, i.e. name.rdf.zip for RDF/XML, name.ttl.zip.

Thanks! In my case, it as name.nq.zip. Did it, but now I have a different error “ERROR: Banner.java:160: Uncaught exception in thread”.

Can you try with a valid file URI such as below?

java -cp blazegraph.jar com.bigdata.rdf.store.DataLoader myfile.properties file:///d:/path/to/dataset/name.rdf.zip

if that doesn't work, please post the Exception.

I've found the right way by passing directly java -cp blazegraph.jar com.bigdata.rdf.store.DataLoader myfile.properties d:\path\to\dataset\name.rdf.zip However, if I rename my zip file .nq.zip or .rdf.zip, there are no errors but nothing is loaded. In contrast, I can load a simple .nq file like this: java -cp blazegraph.jar com.bigdata.rdf.store.DataLoader myfile.properties d:\path\to\dataset\name.nq Would that mean there Blazegraph does not digest .zip?

What version are you using? The relevant code should detect the RDFFormat based on the .zip or .gz extenstion.

Indeed, I see that in the code but... I downloaded the version on sourceforge on the 21rst, December (v 2.1.4?). It's the .jar file hosted in sourceforge without building myself. That was the latest version. Have you released a new version? Btw I just download a new .jar and after starting it says buildVersion=2.1.1 while the one I was testing against is buildVersion=2.1.4. Is it normal?
