hey Hogg, Im a grad student trying learn spark by my own, thanks for the video. Clear and helpful video. The little clip really get me to subscribe, it reminds me of the day when i was back in undergrad, walking to classroom in snow.
Professor, the lambda x+y has me stumped. what if there were three 1s at index 1? for example if the tuple were (2, [1,1,1])? What is the x and y that is being sent as a parameter to the lambda function?
@@AL3Ymir The result is trivial, but no, it's actually kinda difficult to understand what's going on here. It's a loop. first time, x is the first 1 and y is the second 1. It adds them to get 2. Next time in the loop, x is 2 and y is the third 1. It sums them to get 3. More info here spark.apache.org/docs/latest/api/python/reference/api/pyspark.RDD.reduceByKey.html
Man, if you could just stop asking people to subscribe. The channel is great and people will subscribe if they think they will need more videos in the future.

This pretty much sums up my BigData course at university! Another great video! Thank you.

x + y simply sums them.

Okay
I agree. But i subscribed anyway.. great content
No, you need to tell people to subscribe because people forget sometimes, but it should not be in the face all throughout the video...
Great 👍
