to_pandas(), to_arrow() fail because case_sensitive doesn't work if column in row_filter doesn't match the case even if case_sensitive is set to False in scan

[leonidmakarovsky]

Apache Iceberg version

0.7.1 (latest release)

Please describe the bug 🐞

I have a table with column business_time_hour (all lower case). If I capitalize one character, to_pandas() (and to_arrow()) fails. My code is snippet is:

from pyiceberg import catalog cat = catalog.load_catalog(**{'type':'glue'}) table = cat.load_table('namespace' + '.' + 'table') scan = table.scan(row_filter = "business_time_Hour = '2024-09-15 05:00:00'", case_sensitive = False)

The above line passes

df = scan.to_pandas()

The above line fails with the following message

ValueError: Could not find field with name business_time_Hour, case_sensitive=True

Please note that 1. I set case_sensitive to False in the scan method. 2. character 'H' in business_time_hour is capitalized while the actual column name has all lower case letters.

thanks for reporting this. it might be due to a bug we recently fixed in #1147.

can you try it against the latest main branch?

Do I need to install the different pyiceberg version to confirm this?

You can test out the main branch by downloading the repo and installing the library in edit mode.

Run this command in your iceberg-python repo directory:

pip install -e .

you can switch back to the official version by

pip install pyiceberg --force

Hi Kevin,

Sorry for the late reply.

So do I go to ~/opt/anaconda3/envs/py311/lib/python3.11/site-packages/pyiceberg and type:

~/opt/anaconda3/envs/py311/bin/pip3 install -e . Because it gives me an error

ImportError: cannot import name 'GenericAlias' from partially initialized module 'types' (most likely due to a circular import) (/Users/leonid.makarovsky/opt/anaconda3/envs/py311/lib/python3.11/site-packages/pyiceberg/types.py)

Is there anyway to just pip install a specific version for testing? like pip install pyiceberg==0.7.1fixtemp? Thanks.

Since youre using conda, maybe something like this to install directly from github source

https://stackoverflow.com/questions/19042389/conda-installing-upgrading-directly-from-github

pip install git+https://github.com/apache/iceberg-python.git
