Dear Instructor .... I started this course with very normal impression but man you are really rocking!!!! You are giving knowledge about Spark concepts which no documents or classes teach .. Thank you so much!!!!!!
You know what Indians rocks really!!! Though this video has few broken English words & slow pace that i have look this at 1.75X speed but simplicity of explaining concepts is mind blowing & 100% layman :) :) :):) ...... I have listened so many spark sessions from data bricks & many-2 English men ,read so many documents but never got any clarity of concepts the way you are explaining here. Your knowledge is awesome!!!
Very informative ... Thanks a lot . But I have one doubt let I have main program so in this case what entire main program will go on executors node or only RDD will execute over executor.s
my dear brother you are missing main component “yarn resource manager(RM)”. in cluster mode when you fire a job from edge node . first the request goes to RM then RM decides where to run driver basically starts application master(aka driver in spark). then spark driver negotiates with RM for conatiners(executers) . spark code runs in executor. in client mode we are already deciding where to run driver. driver negiotes with yarn for its executors
SPARK DRIVER ----> Req goes to the ------> Cluster Manager (Resource Manager) it can be (1.Stand alone single node spark, 2. Yarn(Hadoop based) , 3. Mesos(Not much in Real time ) ------> Cluster manager decide to send request to diff cluster(Workers) where execution does it can be multiple executers depend on Job.
My question is that if my single machine has same configuration like cluster then what will be different? I have two option option 1 4 system with 8 core and 64 GB ram or single system with 32 core and 256 GB ram. now what will be different if i run client mode in option 2 system or cluster mode in option 1 system.
So this is why in client mode, before I create the spark session, I can access files on the machine I'm on. So like loading a config file or something. If I'm in cluster mode I need to send the file via the --files parameter.
video could have been for 5 minutes and crisp and clear if everything was prepared already in ppt and you not having to draw and explain mutlitple times.

Beautiful explained. Fantastic video. Thanks for making it and explaining us with so simplicity.
The best video for Spark Client Mode Vs Cluster Mode , everything is explained very simply ... thanx a lot
Thank you, almost none of the tutorials paid or free, never once talk about "edge node". It's more clear how spark actually accesses the cluster.
Great explanation. Thank you

Very detailed informative... u r amazing.... thx...

Thanks for adding an important point
Just trying to clear it up, the driver program runs inside an application master process or driver is the same as AM?

Thanks for giving valuable information bro!!
great yrrr...! 🔥🙏🏿
Nice explanation sir..thanks
very good explanation

Can u pls post a video on production deployment in real time project example..
Thanks for explanation. This video gives good idea on both spark modes.
Perfect explanation..!!!
Thank you , Please let me know if you can provide help one to one, I have some questions
Thank you! Clear explanation
Very well explained!
It will great if you have slides instead of writing during the presentation. Lot of time can be saved that way.
Good explanation. Thanks!
Great tutorial, thank you!

Thanks for explaining 👏👏
Hi ,
Could you please explain how to decide number of executor, driver memory,exector memory,number of cores

I have a doubt. So what is exactly a edge node?. Is it kinda master/worker node?.
edge node is worker node which give us access to cluster (every edge node is worker node but every worker node is not edge node)
can edge and cluster node be the same?
Any disadvantages of Cluster mode???
thanks for the video
Very food super
U didn't explain what is driver program in this tutorial
No one explain like this ...diff between driver vs client mode of deployment
bhai jaan nikal di....itna slow...u could have explained it in 10 mins.... woh toh knowledge badhiya hia isliye...thanks anyway

Too slow!
Well explained. Thanks a lot
Nice explanation
