mount s3 bucket with specific endpoint

New Contributor III


  • AZURE-Databricks
  • Language: Python

I can access my s3 bucket via:

boto3.client('s3', endpoint_url='', ... )

and it also works via:

boto3.resource('s3', endpoint_url='', ... )

As a next step, I want to mount this S3 with the specific endpoint in AZURE-Databricks, but there is not even an option for that.

How do I have to write the mount routine in the notebook?


Esteemed Contributor III

In AWS Console, in "My security credentials," please generate a new access key and secret key,

Set them as env variables:

sc._jsc.hadoopConfiguration().set("fs.s3n.awsAccessKeyId", ACCESS_KEY)
sc._jsc.hadoopConfiguration().set("fs.s3n.awsSecretAccessKey", SECRET_KEY)

Now you can read files from your S3 bucket directly

 df ="”", header=True, inferSchema=True)

you can as well mount a bucket permanently using that command

dbutils.fs.mount(f"s3a://{ACCESS_KEY}:{SECRET_KEY}@{aws_bucket_name}", f"/mnt/{mount_name}")

It is safer to use a key vault to store your access key and secret key

This won't work. I'm using AZURE-Databricks and I want to read/write objects from/to an S3 bucket with a specific endpoint → endpoint_url=''

So this is not a I/O operation from Databricks to AWS. In addition, this is actually important because the Azure-Datafactory only support reading and NOT writing back. So far, there's no user-friendly way to do so.
