Databricks Community

I am looking to convert pkl file to parquet format. I am reading this data from Azure Data Lake and convert and create parquet file outputs to store them in my hive metastore.  

Looking for some help. If anyone has worked with nested json file in Databricks notebook. I am trying to parse nested json file to get coordinates and use that to create polygon for footprint. Do I need to read it as txt? How can I use the Databricks...
