databricks - no response when executing command in terminal 'export DATABRICKS_CONFIG_FILE="dbfs:/FileStore/tables/partition.csv'

Question

I am trying to export the csv file by following this guide https://docs.databricks.com/dev-tools/cli/index.html , but there's no response when executing below command, it looks like exist the command directly without saying exporting is successfully or failed.

I have finished install the cli and setup authentication by entering a host and token in mac terminal by following the guide as well.

export DATABRICKS_CONFIG_FILE="dbfs:/FileStore/tables/partition.csv"

please refer to this screenshot: At first, I write the dataframe into file system by below code

df.coalesce(1).write.mode("overwrite").csv("dbfs:/FileStore/tables/partition.csv")

how could i successfully export the file from databricks and where does it stored locally?

Answer 1

Yes, you can copy to your local machine or move to another destination as needed

Configure azure CLI with azure databricks:

Please follow this steps:

• pip install databricks-cli

• Use databricks configure --token command

• Mention Azure databricks host name : https://adb-xxxxx.azuredatabricks.net/

• Past your Personal Access Token .

Now all set to export the CSV file and store it in a destination location.

databricks fs cp dbfs:/FileStore/tables/partition.csv dbfs:/destination/your_folder/file.csv

databricks fs cp C:/folder/file.csv dbfs:/FileStore/folder

Or

If you have a lot of CSV files placed in a folder.you prefer to export the entire folder rather than individual files.

Use -r to select your folder instead of the individual file.

databricks fs cp -r  dbfs:/<folder>  destination/folder

Alternative approach in python:

You can use directly dbutils.fs.cp("dbfs:/FileStore/gender_submission.csv","destination/folder")
