            I think encoding the file from here should solve the problem. So you add encoding="utf8" to your tuple of the variable listings_df.

            Like shown below;

            listings_df = spark.read.csv("listings.csv", encoding="utf8", header=True, mode='DROPMALFORMED')

            I have not defined any schema or table in Postgres. But I want the loading process to automatically infer the schema on read and create a table, then load the SparkSQL dataframe into that table.

            Don't try to install everything in a single environment. Create a Python environment and create an R environment, and make sure they each have their respective kernel packages (ipykernel, r-irkernel) so that they can be used in Jupyter.

            ANSWER

            Answered 2021-Jun-02 at 02:56

            The exit code 8 is likely from wget meaning an error response from the server. As an example, this path that the Dockerfile tries to wget from isn't valid anymore: https://www.apache.org/dyn/closer.lua/spark/spark-3.0.1/spark-3.0.1-bin-hadoop2.7.tgz

            From the issues on the repo, it appears that Apache version 3.0.1 is no longer valid so you should override the APACHE_SPARK version to 3.0.2 with a --build-arg:

            There are several problems in your setup:

            • You don't add the package for Kafka support as described in docs. It's either needs to be added when starting pyspark, or when initializing session, something like this (change 3.0.1 to version that is used in your jupyter container):
