Mam you are awesome.. teaching talent with example is like god gifted us.....
Mam, can u briefly tell me if we use yarn, then what would be the role of the cluster manager and its application master in spark.. because driver directly communicating to executor

[@khajaabdulmujeebbasha6327]

mam there is shuffle in coalese even it is considering as narrow transformation why?

[@angelangeli2089]

good explanation and easy!! :)

[@geetakadam6728]

Hello Mam I had gone through your video the way you have delivered is very nice.
I have one dought though silly but I wants to know in local system that means on our laptop when we execute pyspark code who is executor and who is worker and on cloud please explain me executor and worker?
Thanks in advance

[@guptaashok121]

Is it driver which reads all data and divide in partition and sends to executor?

[@BigDataThoughts]

Yes executors job is to just execute.

[@guptaashok121]

@@BigDataThoughts will it not create bottleneck..

[@BigDataThoughts]

@@guptaashok121 no it won't be cos actual data resides on executors, driver is just the coordinator. while assigning task principal of data locality is kept in mind.

[@guptaashok121]

@@BigDataThoughts that's what my doubt is, if driver is not reading the data then how it sends command to executor on which data to work on
