I want read a json from IO variable using PySpark.

My code using pandas:

io = BytesIO()

ftp.retrbinary('RETR '+ file_name, io.write)

io.seek(0)

# With pandas

df = pd.read_json(io)

What I tried using PySpark, but don't work:

io = BytesIO()

ftp.retrbinary('RETR '+ file_name, io.write)

io.seek(0)

df = spark.read\

.format("binaryfile")\ # I already tried with format "json"

.option('inferSchema', 'true')\

.option('header', 'true')\

.json(io)

Obs: Is not possible save in a file and read that after
