Many Thanks.. you are simply superb... one of the best resources available on internet...best part of all workshops you share is its always having practical content... truly appreciable...Many Thanks...
wow wow wow ... just awesome Sir... Thank you so much for this beautiful time consuming job for all the beginners to learn from your knowledge... Thank you once again🙏🙏
Once again, this is a great tutorial. Thank you. I was wondering what is your view on running Spark ETL on both AWS Glue and Amazon EMR Spark cluster, what would be your preference between these two services assume the AWS cost isn't of concern?
if you keep cost aside - the primary difference is - 1. Glue is Serverless . EMR is IaaS 2. Glue has scheduling, workflow mechanism in place. EMR needs support from other services like CloudWatch and StepFunctions. 3. Glue support scala, pyspark and python shell only. EMR support wider frameworks such as Hive, Pig and HBase. So, my recommendation is to use Glue if working around scala, python and pyspark. But if you are using Hiv or Pig like programs, EMR is the choice. Hope it helps,
Sir can we get a dedicate playlist to master EMR or any other open source resources for more help to learn from scratch like you instructed here with the pattern of teaching new things and implementing at the same time, if possible plesas prepare a dedicated EMR targeting playlists. Jai Hind
Hi first of all thank you for this video. my question is while i successfully created cluster and notebook but my jupytor notebook says kernel error. unable to solve it. my cluster is ready to use.
Not sure I get the question. Why would you call notebook using boto3 to the job? if you want some data processing; simply create EMR task and submit it. Hope it helps.
I tried the workshop by myself. I followed all the steps carefully. When I tried PySpark programming for running tasks using Notebook; I click on run and nothing happens. I do not see anything in the output folder. Please help
for the step 5 when you write code in Jupyter notebook. Can you please share the output of the each of the code statements you are running. That might give me some clue.
@@AWSTutorialsOnline I tried again. I tried the first line of code(to import library). I copied the code and clicked run(as per steps in the tutorial), it does not give me any output and directly jumps to the new line.
Hi - I published a workshop which can help you. Here is the link - aws-glue-pyspark-lab.s3-website-eu-west-1.amazonaws.com/labs/ It talks about working with Glue Data Catalog and Redshift cluster. But the same code can be used with Postgresql as well. Hope it helps.
@@AWSTutorialsOnline thanks for the inputs. But, if we use jdbc connection in dynamic frame to write the data into rds will get performance issues. Is there any way to do this?
Suppose I have 1 Master and 1 Core Node in EMR. [ df = spark.read.csv("s3://...../demo.csv") ] I submit this task in EMR. After executing this line of code I should have data in the dataframe. But is that demo.csv data getting saved in HDFS also? If yes, then how can I find that demo.csv data in HDFS. And if no, then where does the data store after reading from S3.
Sorry Rishi, I somehow missed your comment. Apologies for that. The dataframe data is stored in HDFS and dataframe is a way to access the data. Dataframe provides a lazy load mechanism to access and process data stored in HDFS.

This is the best tutorial I have seen
Thanks
Great introductory tutorial to AWS EMR. After watching your tutorial I now have some knowledge about EMR. Thanks a lot.
Glad it was helpful!
Excellent presentation described in simple language. Really appreciate your effort.
Glad you liked it
Its really good session as a beginner i learned many things thank u soo much
Glad to hear that
Very good tutorials and demos.
Glad you like them!
Awesome😊... Really helped alot... Looking one more session on read write hbase table from spark in EMR along with version compatibility...
Sure - will work on it
Great job. Exactly what I needed. Thanks a ton
You're welcome!
great content. focuses on the basics and gets into the right level of details. amazing job !
I would love for you to do a pyspark tutorial.
I already have a pyspark tutorials. Please check my channel.
Masterpiece content
Many Thanks
Great video!
One small correction: it's Jupyter Notebook
Amazing, thanks for the great introduction!

@@AWSTutorialsOnline Agree 100%.
@@AWSTutorialsOnline How u can chose now between glue and emr ? bc they both serverless now
Very informative video, please do tutorial for Glue and Athena as well
There many videos on Glue and Athena in my channel. If you want any specific topic which is not there, please let me know.
Very helpful and informative
Glad you liked it
good job! i liked it a lot, keep doing an awesome job!
Really Useful. Thanks for sharing the knowledge😃

Thanks sir making such video..

@@AWSTutorialsOnline any idea how do i download jupyter notebook running in EMR as .py file so that can be uploaded to s3?
This is amazing 👏🏽
Many thanks

Hi first of all thank you for this video.
my question is while i successfully created cluster and notebook but my jupytor notebook says kernel error. unable to solve it. my cluster is ready to use.
Try restarting notebook kernel. It generally fixes any issue.
great content. but someone can tell me how to fetch input parameters in the notebook when EMR notebook being hit through boto3 or any backend language
Not sure I get the question. Why would you call notebook using boto3 to the job? if you want some data processing; simply create EMR task and submit it. Hope it helps.
Excellent👍👍👏
Thank you very much
@@AWSTutorialsOnline do you also teach bigadta on cloud any such program available if so please message me
How can i create a cluster with emrfs in stead of hdfs? Great video btw.
Awesome video. from where we can download the jar file?
I don't think you can. It is located on the Amazon EMR AMI for your cluster.
What to choose under "New" option if I will be doing Scala code in Spark instead of python?
this is brilliant, thank you
Glad you liked it!
Good work
Thank you so much 😀
its very helpful

How we can use Presto with Emr ? If you can share a document or tutorial I can refer ?
thanks
You're welcome!
can plz give workshop on aws emr hadoop and presto
Sure - I will plan for it. Thanks for the feedback.
I tried the workshop by myself. I followed all the steps carefully. When I tried PySpark programming for running tasks using Notebook; I click on run and nothing happens. I do not see anything in the output folder. Please help

What is the best way to load aws glue catalog data into rds(postgesql)?
Please help me understand - you have data in S3 which you have cataloged in Glue. You want to move data to RDS (postgresql). Is this the requirement?
