Bug

What happened:
The unit test failed during the process of reading the data from the blob storage located in the Azurite container.

from deltalake import DeltaLake

AZURE_STORAGE_CONNECTION_STRING = "DefaultEndpointsProtocol=http;AccountName=devstoreaccount1;" \
                                  "AccountKey=Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsu" \
                                  "Fq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw==;" \
                                  "BlobEndpoint=http://127.0.0.1:10000/devstoreaccount1"

def test_load_data_from_table_in_delta_format_located_in_azure_storage_with_valid_connection_string(rp_logger):
    rp_logger.info("Loading data from the table in Delta format located in Azure Storage "
                   "with valid 'AZURE_STORAGE_CONNECTION_STRING'")
    path = "azure://test-container/delta_tables/table_with_data"
    table = DeltaTable(
        path,
        storage_options={
            "AZURE_STORAGE_CONNECTION_STRING": AZURE_STORAGE_CONNECTION_STRING,
            "AZURE_STORAGE_ACCOUNT_NAME": "Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsu",
            "AZURE_STORAGE_ACCOUNT_KEY": "devstoreaccount1",
            "allow_http": "true"}
    )
    df = table.to_pandas()

    assert assert_frame_equal(
        df, pd.DataFrame(
            {
                "gender": [0, 1, 0, 1],
                "height": [157.18518021548246, 166.7731072622863, 162.91821942384928, 173.51448996432848],
                "id": [925, 84, 821, 383]
            }
        )
    ) is None

    assert isinstance(df, pd.DataFrame)
    rp_logger.info(SUCCESSFUL_MESSAGE)

There is the following error:

deltalake.PyDeltaTableError: Failed to load checkpoint: Failed to read checkpoint content: Generic MicrosoftAzure error: Error performing get request delta_tables/table_with_

account name and account key are switched :). for azurite you do have to pass the option "use_emulator": "true" though, since we have not implemented connection string parsing, and the url handling for azurite needs to be a bit different.

Thank you a lot for your help) It works

Great, I'll close the issue then :).
