How do I read a parquet in PySpark written from Spark?

Question

I am using two Jupyter notebooks to do different things in an analysis. In my Scala notebook, I write some of my cleaned data to parquet:

partitionedDF.select(\         


        

Answer 1

You can use parquet format of Spark Session to read parquet files. Like this:

df = spark.read.parquet("swift2d://xxxx.keystone/commentClusters.parquet")

Although, there is no difference between parquet and load functions. It might be the case that load is not able to infer the schema of data in the file (eg, some data type which is not identifiable by load or specific to parquet).
