Hello @Ajay Prasadh Viswanathan ,
Welcome to Microsoft Q&A platform.
To read via spark methods from mount points you shouldn't include the /dbfs/mnt
as /dbfs/mnt/ajviswan/forest_efficiency/2020-04-26_2020-05-26.csv
prefix, you can use dbfs:/mnt
as dbfs:/mnt/ajviswan/forest_efficiency/2020-04-26_2020-05-26.csv
instead.
Hope this helps. Do let us know if you any further queries.
