File too large json.dumps

Tried to dump an index which is more than 300+ MB, and run into

$ es2csv -q '*' -i 'metrics-2017.10.20' -o /tmp/test.csv -u http://172.18.0.2:9200

Hello, what filesystem are you using? This error is weird. I have been worked with indexes which is more 1 GB size with out any issues.

Cannot reproduce. maybe due to lack of space in the hard drive. Thanks for answering.
