Rinke Hoekstra created ARROW-7226:
-------------------------------------
Summary: [JSON] Json loader fails on example in documentation.
Key: ARROW-7226
URL: https://issues.apache.org/jira/browse/ARROW-7226
Project: Apache Arrow
Issue Type: Bug
Reporter: Rinke Hoekstra
I was just trying this with the example found in the pyarrow docs at
[http://arrow.apache.org/docs/python/json.html]
The documented example does not work. Is this related to this issue, or is it
another matter?
It says to load the following JSON file:
{{{"a": [1, 2], "b": {"c": true, "d": "1991-02-03"}}}}
{{{"a": [3, 4, 5], "b": {"c": false, "d": "2019-04-01"}}}}
I fixed this to make it valid (but that's another issue):
{{[{"a": [1, 2], "b": {"c": true, "d": "1991-02-03"}},}}
{{{"a": [3, 4, 5], "b": {"c": false, "d": "2019-04-01"}}]}}
Then reading the JSON from a file called `my_data.json`:
{{from pyarrow import json}}
{{table = json.read_json("my_data.json")}}
Gives the following error:
{code:java}
