cfis opened a new issue, #1018:
URL: https://github.com/apache/datafusion-python/issues/1018
This might be more of an arrow issue, but I am running into this error:
`Exception: DataFusion error: SchemaError(DuplicateQualifiedField {
qualifier: Bare { table: "data" }, name: "year" }, Some(""))`
This is happening when querying parquet files stored on S3 using hive
partitioning. The partition fields are year/month/day. Those same fields are
also contained in the parquet files themselves. Thus the error. Is there a way
to avoid this? I can specify the schema manually but I'd like to avoid that.
Example Code:
```python
import os
import time
import datafusion
from datafusion.object_store import AmazonS3
s3 = AmazonS3(
bucket_name="<removed>",
region="<removed>",
endpoint="<removed>",
access_key_id="<removed>",
secret_access_key="<removed>")
ctx = datafusion.SessionContext()
ctx.register_object_store("s3://<removed>/", s3)
ctx.sql("""
CREATE EXTERNAL TABLE data
STORED AS PARQUET
PARTITIONED BY (year, month, day)
LOCATION 's3://<removed>/'
""")
sql = f"""SELECT count(*)
FROM data
WHERE year = 2025 AND
month = 1 AND
day = 1)
"""
```
