             Summary: Support reading Parquet files from Stream Buffer
                 Key: SPARK-30242
                 URL: https://issues.apache.org/jira/browse/SPARK-30242
             Project: Spark
          Issue Type: Wish
          Components: Spark Core
    Affects Versions: 2.4.4
            Reporter: Jelther Oliveira Gonçalves


Reading from a Python BufferIO a parquet is not possible using Pyspark.



Using:

 
{code:java}
from io import BytesIO

parquetbytes : Bytes = b'PAR...'

df = spark.read.format("parquet").load(BytesIO(parquetbytes))
{code}
Raises :
{code:java}
java.lang.ClassCastException: java.util.ArrayList cannot be cast to java.lang.String{code}
 

Is there any chance this will be available in the future?
