> Key: ARROW-8258
> URL: https://issues.apache.org/jira/browse/ARROW-8258
> Project: Apache Arrow
> Issue Type: Bug
> Components: Rust
> Reporter: Andy Grove
> Assignee: Renjie Liu
> Priority: Major
> Fix For: 0.17.0
>

> I discovered this bug with this query
> {code:java}
> > SELECT tpep_pickup_datetime FROM taxi LIMIT 1;
> General("InvalidArgumentError(\"column types must match schema types,
> expected Timestamp(Microsecond, None) but found UInt64 at column index 0\")")
> {code}
> The parquet reader detects this schema when reading from the file:
> {code:java}
> Schema {
> fields: [
> Field { name: "tpep_pickup_datetime", data_type: Timestamp(Microsecond,
> None), nullable: true, dict_id: 0, dict_is_ordered: false }
> ],
> metadata: {}
> } {code}
> The struct array read from the file contains:
> {code:java}
> [PrimitiveArray<UInt64>
> [

> 1567319357000000,
> 1567320092000000,
> 1567321151000000, {code}
> When the Parquet arrow reader creates the record batch, the following
> validation logic fails:
> {code:java}
> for i in 0..columns.len() {
> if columns[i].len() != len {
> return Err(ArrowError::InvalidArgumentError(
> "all columns in a record batch must have the same
> length".to_string(),
> ));
> }
> if columns[i].data_type() != schema.field(i).data_type() {
> return Err(ArrowError::InvalidArgumentError(format!(
> "column types must match schema types, expected {:?} but found
> {:?} at column index {}",
> schema.field(i).data_type(),
> columns[i].data_type(),
> i)));
> }
> }
> {code}
