Spark Dataframe validating column names for parquet writes

For everyone experiencing this in pyspark: this even happened to me after renaming the columns. One way I could get this to work after some iterations is this:

file = "/opt/myfile.parquet"
df = spark.read.parquet(file)
for c in df.columns:
    df = df.withColumnRenamed(c, c.replace(" ", ""))

df = spark.read.schema(df.schema).parquet(file)
