I forgot to run it with stacktrace, someone suggested that I use groovy and batch-inserter <https://gist.github.com/jexp/0617412dcdd644fd520b#file-import_kaggle-groovy>, and I am trying that right now. If I could not load the data using this approach, I will run batch-import again with --stacktrace to find the error message.
