Marklogic Content Pump Issue

I am trying to load a dbPedia dataset in .nt format into MarkLogic using the MarkLogic Content Pump. I'm using MarkLogic 7, with an XDBC server running on port 8005 on my machine. My data is present in a file, persondata_en.nt, and I am using the following command to load it. 

C:\mlcp-Hadoop2-1.2-1\bin\mlcp import -mode local ^
-host localhost -port 8005 -username admin -password admin ^
-input_file_path "C:\dbp\persondata_en.nt" ^
-input_file_type RDF

This command results in a Premature EOF exception, as below.

I'm using pretty much the same command as specified in the example load scripts in the tutorial here. Has anyone faced this problem before? Any help would be great. Thanks!

Solution

  • Thanks for your help guys. I managed to figure out the reason for the issue. I had not configured the settings for the MarkLogic XDBC server properly. I reset the server following the instructions from the documentation, and was able to successfully insert triples into the store.
