when i run fuseki, I find my dataset Movies, but when i upload the .nt file, i get this error:

Result: failed with message "SyntaxError: JSON Parse error: Unrecognized token '<'"

The file is from offical movie, here http://www.cs.toronto.edu/~oktie/linkedmdb/ and the name of the file is: linkedmdb-latest-dump.zip (about 41MB), please download it and unzip it, then you will get the file .nt

Update 1

It sounds like even when i use a correct .ttl file, i have the same problem, probably it is no correct my confige.ttl file, could you check please ?

Update

Even with this data

@prefix : <http://example.org/rs#>
@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#>

:A   rdfs:subClassOf :B .
:B   rdfs:subClassOf :C .
:i  a   :A .

I still get the same error

Help please

why is it giving a "JSON Parse error" when the file is not JSON? is Fuseki trying to interpret it as JSON (for some reason)? — CaptSolo, Mar 16 '16 at 15:07

One thing that strikes me as odd in your config.ttl file is that you have not enabled the Fuseki upload service:

<#service1> fuseki:serviceUpload "upload" ; # Non-SPARQL upload service

I seem to remember that you need to enable that service to use file uploads in the UI, but I don't remember for sure.

Wanted to post a comment but could not due to my low reputation. So posting here.
I wanted to know if you ever found solution to this issue. I am trying to parse the same dataset using python (rdflib) and I am also getting parse error. Now, I am wondering if there is a problem with the dataset.
Syntax:

from rdflib import Graph
g = Graph()
g.parse("path_to_file/linkedmdb-latest-dump.nt", format="nt")

Error Message:

rdflib.plugins.parsers.ntriples.ParseError: Invalid line:u'<http://data.linkedmdb.org/resource/country/iso alpha2> .'
