thisisnic opened a new pull request #9950:
URL: https://github.com/apache/arrow/pull/9950
A couple of things I wanted to check are expected behaviour:
1. If I specify in the schema that a numeric column should be a string
column, I get the error `Error: Invalid: JSON parse error: Column(/third_col)
changed from string to number in row 0`
(e.g. if I run the following)
```
tf <- tempfile()
writeLines('
{ "hello": 3.5, "world": 2, "third_col": 99}
{ "hello": 3.25, "world": 5, "third_col": 98}
{ "hello": 3.125, "world": 8, "third_col": 97 }
{ "hello": 0.0, "world": 10, "third_col": 96}
', tf)
read_json_arrow(tf, schema = schema(third_col = float64(), world =
float64()))
```
2. As can be seen in the tests output (will delete the `print` statements
before this is merged), table columns are returned in the order specified in
the schema and then the columns not mentioned in the schema.
