[BUG] Reading JSON file saved from Series fails

[drabastomek]

Describe the bug Reading a JSON file created from a Series .to_json(path, orient='records', lines=True) call leads to a Input data is not a valid JSON file when trying to read with .read_json(path, orient='records', lines=True) (with or without engine='cudf' parameter).

NOTE: this is only a problem when saving Series in this format -- DataFrame objects are saved properly.

Steps/Code to reproduce bug

cudf.Series([1,2,3,4,5]).to_json('sample.json', lines=True, orient='records')

cudf.read_json('sample.json', lines=True, orient='records')

The output file looks as follows:

1
2
3
4
5

Expected behavior The file is read back properly and produces a valid cudf.Series object.

Environment overview (please complete the following information)

• Environment location: Docker
• Method of cuDF install: Docker
  • RAPIDS v 0.16 pull from nightly.
