python - databricks:检查挂载点是否已挂载

Question

如何在databricks python中挂载之前检查挂载点是否已经挂载？

dbutils.fs.mount

谢谢

Answer 1

试试这个:

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')

结果:

/mnt/flightdata 已卸载。

以此验证:

dbutils.fs.ls("/mnt/")
