Thank u so much sir
Excellent .. can’t be explained more simpler than this
John doe reaching out
hihi... do you have notes how to relocate the Derbydb files onto persistnt storage, thus allowing for the container to be killed, recreate and the metastore it had persists. At the moment imoved the DerbyDB off to PostgreSQL but it adds weight/complexity to the build.
the best video i have even seen on installing spark in ubuntu. keep doing great work my brother
Easy to follow setup, kudos to the creator.
You will need a company email address to install and practice with Query Surge. If you don't have a company email, you may also use a college email address if available
I am searching a job so i don't have company email id what I will do
so helpful to understand total concepts.
Clister clear explanation bro🎉 But no reach 😢😢
Don''t waste your time here this is most useless installation video I ever saw..
Thanks, it works!!!
mine is showing no file directory
Thanks!!!
no im not feeling awsome
Very Informative Video. Thank You..🙂
I had a question here sir .... So the logical Plan which is created by Catalyst Optimizer can we called it a Linage and same goes for physical plan can we call it as DAG ?
No, lineage and logical plan are not the same. Lineage in Spark refers to the sequence of transformations that lead to the creation of a DataFrame or RDD (Resilient Distributed Dataset), whereas the logical plan is an abstract representation of the query or operations to be performed, which can be either resolved or unresolved. Yes, the DAG (Directed Acyclic Graph) is based on the physical plan, which is Spark's final execution plan.
Thank You! So much Sir your guidance to install apache airflow make me able to install it easily. Thanx for your kind cooperation in this regard.
I'm getting error while initializing db
Great explanation 😃👍🏻....thankuu so much sir 😇
Thank you for your support 😃
Still on mapR?
Im getting error "this site cant be reached, localhost refused to connect"
@bernatferrer425 Could you email the screenshot of error to learn@blismosacademy.com
Thank you for a video. But I have a question. During the command "airflow scheduler" one operation was repeating and repeating " adopting or resetting orphaned tasks for active dag runs" and it didnt finish, what should it be? Thank you!
I need etl automation testing course
this is great !
ive managed to install and configure airflow but having issues running the DAG when i try to trigger it i keep getting the error that DAG is not found in DagMOdel
Could you please share the screenshot at learn@blismosacademy.com
*promo sm* 😪
Excelent video and explanation
Can I get your number sir ?
Sure, +91 7892528411 and also you can check our Website for more information www.blismosacademy.com
thanks from Brazil!
Mahantha sir great♥
Hi , thanks for the video. it's very informative. After airflow scheduler command what shortcut did you use to stop it and go to next airflow webserver command. Thanks in advance.
Thank you for your message!!!! You can use the keyboard shortcut Control+Z. Alternatively, you may open a new terminal and type "Airflow webserver."
After running beeline -u jdbc:hive2://, getting this 0: jdbc:hive2://(closed) And if I run any query, getting this Connection is already closed How to resolve this issue?
Instead of using beeline -u jdbc:hive2:// you can invoke hive by using hive command in the terminal. If you again get any error please mail the screenshot to learn@blismosacademy.com
do we need to install sqlite before installing airflow?...I am getting error when i run airflow scheduler command
No Pradnyasutar, SQLite is not required for Airflow installation You can mail the screenshot to learn@blismosacademy we will guide you with the installation
@@blismosacademy ok thanks
@@pradnyasutar6910 @pradnyasutar6910 hey I'm getting the same error too. how did you solved it
Thank you for the nice walk-through👍
This finally cleared up the issues I was having understanding the abstraction layer Hive represents. I understood Hive was a collection of data in HDFS, or some other distributed file system, but I was confused on how that was, why it was and what it did to make that work. I knew the meta store played a role but I was also confused on how data even gets inserted into hive because it feels like a database so again, that abstraction was confusing. This video cleared it all up! You earned a sub. Thanks a ton.
Thank you so much for your comment!!! We are happy that you got the better understanding of Hive
I have followed along with you but I am getting this error any help /opt/spark/spark-3.4.0-bin-hadoop3/bin/spark-class: line 71: /usr/lib/jvm/jdk-11.0.19/bin/java: No such file or directory /opt/spark/spark-3.4.0-bin-hadoop3/bin/spark-class: line 97: CMD: bad array subscript
Hello @moeal5110, Delete the previous spark-3.4.0-bin-hadoop3 file and Install the new Spark File on home i)Instead of this /opt/spark<file_Path> just ii)Click on home -> open the terminal -> get the path of the file using pwd command and paste it in the bashrc file and save it and again start the spark Please do follow the above steps and if you get any error or issues reach out to us: learn@blismosacademy.com
GOOD CONTENT
Thank you!
thank you, this was a very clear video and explanation on the Hive metastore
Thank You!!!
when you were inserting the data with standalone mode (with insert query) into customer/orders table in hive, which file format got created in warehouse dir ? was that ORC ? (the file having name like 000000_0)
Please provide your number
It's worth knowing that you can use cat > a_file_name and then type the contents of the file at the command line, like using a heredoc in a script. (I like doing this when writing short scripts as I can see the contents of the terminal as I write it, and it is a good challenge in thinking before you type.)
Thank you sir 🙏
