believe it bro this is what real time code looks like.i have gone through minimum 10 courses in udemy and etc.but you will not find this.Very nice.DO YOU HAVE ANY UDEMY TUTORIAL??do you give tution
I was struggling to derive schema from a json file and your video came as an alternate approach. I firstly made list of dictionaries from json and then traverse through that list and create structtype as shown by you. Thanks alot bro…keep growing & helping community 😊
Bro, I have followed the video to create the Python functions/Module and .ini conf file. When I applied the schema generated, I could see the exception. Below is the code snippet and exception, could you please write your review and unblock me : Code Block: jsonValDf = valueDf.select(F.col("key"), F.col("topic"), F.col("partition"), F.col("offset"), F.col("timestamp").alias("KafkaTime"), F.col("DbxTime"), from_json(col("value"), landingStructSchema).alias("valueData")) Exception: AnalysisException: Cannot parse the schema in JSON format: Failed to convert the JSON string '{"metadata":{},"name":"UniqueFileIdentifier","nullable":"True","type":"string"}' to a field.
Awesome way to define schema in pyspark.. I have a question .. how can I pass Decimal type in this function ? As we have different value for decimal type.. Thanks in advance
Hi bro, i am facing hell issue to install pyspark in windows 64 bit machine.would you please make a video clearly of installation pyspark.please requesting.

Osm explanation totally loved it thanks for your time ☺️ to share your knowledge
Your spark video series is really very good and much helpful. It will be nice if you post video series of Hive and Sqoop also.
This is exactly what i was looking for. Awesome.
Awesome, Excellent this is real time works happen. Keep posting like this. Though I am primarily working in Scala but I will translate it 😊
in case of array type or maptype what should i do??
What an explanation, loved it..... Thank you
This is what, i have been looking for.!! Thanks.
