im using pyspark 2.4 to consume from Kafka, but when casting the Value column that contain the messages
it appears like that == > like in the table below => �����īVAL ,
knowing that im just consuming ( i do not know how the producer was made)
i just know that its sent from postgre to kafka topic ,
then i consume it via pyspark from this kafka topic
and the sent data is JSON
is there somethin wrong with my consumer ?
kafka_messages : DataFrame = self.sparkSession.read \
.format("kafka") \
.option("kafka.bootstrap.servers", self.bootstrap_server) \
.option("kafka.security.protocol", "SASL_PLAINTEXT") \
.option("subscribe", self.topic) \
.option("startingOffsets", offset_option) \
.load()
def decode_and_flatten_msg_value(df, schema) -> DataFrame:
df = (
df
.select(df['value'].cast('string'))
.select(F.from_json(F.col("value"), schema).alias("data"))
.select("data.*")
.na
.drop('all')
)
return df
here an example of the message before cast to string the value column :

Is there any config in snort I can change to make this happen?
Thanks in advance for any help!

I'm not sure what you mean by decrypting this so you can view it. It looks like the contents of an image file. Try opening this file with an image viewer such as MS Paint, Adobe Photoshop or try uploading it to https://pixlr.com/editor. You might have to change the file extension for this to work (try PSD).
In case you're not interested in the image but actually the contents of the file, encoding is not really your problem here since this is not a text file but a binary file. Its contents don't represent characters but are contents of data structures used by Photoshop to represent an image.
Here's a chunk of the raw data:

It's a hex dump and I'm interested in isolating the text part.
Here's a sed expression that almost works:
$ sed 's/.* |\([a-zA-Z0-9:& \.]*\)|$/\1/g' hex.dat

Almost. But how to filter that last line though?
$ sed 's/.* |\([a-zA-Z0-9:&\[\] \.]*\)|$/\1/g' hex.dat
And:
$ sed 's/.* |\([a-zA-Z0-9:&\\[\\] \.]*\)|$/\1/g' hex.dat
Don't work at all (they fail to translate anything).
And:
$ sed 's/.* |\([a-zA-Z0-9:&[] \.]*\)|$/\1/g' hex.dat
obviously can't work.
Thanks for any help.
You almost had it.
Look at this section of a Unix regular expressions tutorial.
The way that yours could be done is by placing ][ immediately after you begin your character class.
So, try sed 's/.* |\([][a-zA-Z0-9:& \.]*\)|$/\1/g' hex.dat
For clarification, it does not matter where in the character class the [ is, so long as the closing bracket you intend to include in your character class (]) immediately follows the opening of your character class.
Also, as a further edit, try typing man cut and using what Tomasz said in a comment.
cut -d='|' -f2 hex.dat will cut your file, delimiting on a pipe, and take the second field.
