This video is to just demonstrate how to get access to community edition and start uploading your file and analyzing it
I will be following this up with detailed walk-through of Spark ML code. In case if you have not seen my Intro to Spark ML you can view it below

Dataset used in this video is available in my git repo here - github.com/srivatsan88/CZcamsLI/tree/master/dataset
awesome video
Do you know if intellisense can be turned on in the notebook? ie dropdowns for functions, columns in a table, etc
For new comers,
The file_location = "/FileStore/tables/..."
Here, FileStore/tables is mandatory,
And after that, you have to write the .csv file name with .csv extension.
Are there any advantages of using Spark in Databricks community edition vs using it in google Colab? Or both will give the same performance? If yes, then what are those advantages?
thanks a lot, keep going
I want a serious help from you..actually I have a sequence data i.e., a single row data I want to split the data into multiple rows after every 5th delimiter ('|') how can I do that??
Thanks, good job
I need help in solve the problem for fee , can you help me
Autoloader perform notebooks orchestration?
Nice thnk u
thanks a lot
Hi Thanks for this video...
where can we check the log or detail when notebook is stuck ...and status is only running..and finally have to cancel it ..what could be the reason
You can check on Spark UI that you can find on top of databricks page. If job is running for long you can check that stage and see if there is any bottleneck that can be fixed
I want to load data directly from local system into the code. I dont want to load data to dbfs and then use it. can you help me?
Mahesh.. Then you have to install pyspark in local.. databricks need file into their environment.. If you do not want to upload you can also pull the file for that session during notebook execution from github or any URL and try. I have some similar sample in my colab demo

Please help me how to re-start the 'Terminated' cluster in databricks. As in this Video you already have a terminated cluster can we re-start the same?
Kush.. Just start a new cluster with same name or different name. In community edition I dont think you can restart it
as far as i know you cant restart it. you should create a new cluster :)
What is the difference between Azure Databricks and only Databricks Analytical Platform?
The functionality is same from data bricks end it is only connectivity to Azure storage services is easy on databricks hosted on Azure and one that is on Amazon connectivity to AWS storage like S3 is easy
I thought apache spark was some quantum physics🙄until this video popped in my recommendations😅..... apache spark here i come💃
I want to import community data using wget directly from http endpoint, I tried using mkdir and wget but I dont see any folder setup in my data. Can you please suggest
%mkdir ../data
!wget -O ../data/aclImdb_v1.tar.gz ai.stanford.edu/~amaas/data/sentiment/aclImdb_v1.tar.gz
!tar -zxf ../data/aclImdb_v1.tar.gz -C ../data
See if below works but wget should also work. You can write in /tmp directory and move to dbfs
%sh curl -O 'ai.stanford.edu/~amaas/data/sentiment/aclImdb_v1.tar.gz'
%fs ls "file:/databricks/driver"
In add data what file u uploaded?
I just used the corona virus dataset that I prepared from john hopkins university
It is in my github
github.com/srivatsan88/CZcamsLI/tree/master/dataset/coronavirus
I'll probably check it out for myself before you answer this, but:
Does the spark connector only have support for Scala?
I did not get it. If language support spark does support python. Spark is written in scala but has python bindings
@@AIEngineeringLife I work with pyspark, I just wanted to know that if inside databricks there was this option. Thank you!!
@@daniela.3851 its supports
i want to pivot data using python that is present in table inside databricks.. how to do that...can you help me ..
by the way..great tutorial
Krishna.. you are asking pivot in python then pandas dataframe has a pivot function. Spark DF as well as pivot and you can check it here - databricks.com/blog/2016/02/09/reshaping-data-with-pivot-in-apache-spark.html
I think I have covered it as part of my SPark transformation videos but do not recollect it
for a community edition on free trial how many clusters can i create?
On community edition it is only one cluster
Are there other databricks videos also on this channel?
Yes.. I have quiet a good number in this playlist - czcams.com/play/PL3N9eeOlCrP5PfpYrP6YxMNtt5Hw27ZlO.html
@@AIEngineeringLife I was following your Apache spark for Data Scientist playlist. I guess it is not sorted sequentially.
@@shubhamtalks9718 Data scientist playlist only focuses on ML but the one I shared focuses on both data engineering and machine learning
What is parquet format in databricks?
Parquet is a file format for storing data. It is columnar format and many processing engine is optimized for it
parquet files are in columnar format, best fit in OLAPs ! the format is efficient for parallel processing .
Nice thnk u
