Jörn Horstmann created ARROW-11648:
--------------------------------------
Summary: [Rust]: Json reader for nested dictionary arrays returns
empty array instead of array of nulls
Key: ARROW-11648
URL: https://issues.apache.org/jira/browse/ARROW-11648
Project: Apache Arrow
Issue Type: Bug
Components: Rust
Reporter: Jörn Horstmann
{code:java}
// schema: id: Utf8, attr: List<Dictionary<Utf8>>
let input = json!([
{"id": "a"},
{"id": "b"},
{"id": "c"},
{"id": "d"},
{"id": "e"},
]);
// Results in ArrowError("InvalidArgumentError(\"all columns in a record batch
must have the same length\")"){code}
Probably related to `list_array_string_array_builder` around line 688:
{code:java}
if let Some(value) = row.get(col_name) {
...
}
// no else{code}
Expected: The resulting array should have a length equal to the number of rows,
all nested lists should be marked as null.
