databricks: check if the mountpoint already mounted
Try this:
def sub_unmount(str_path): if any(mount.mountPoint == str_path for mount in dbutils.fs.mounts()): dbutils.fs.unmount(str_path)sub_unmount('/mnt/flightdata')Result:
/mnt/flightdata has been unmounted.
Verify with this:
dbutils.fs.ls("/mnt/")Inspired by this:https://forums.databricks.com/questions/8103/graceful-dbutils-mountunmount.html
Open a new cell in Databricks notebook and write the below command:
%fs mounts
As an output, you will get mountpoint, path, and the encryption type.
