Dear Members,I need your help in below scenario.I am passing few parameters from ADF pipeline to Databricks notebook.If I execute ADF pipeline to run my databricks notebook and use these variables as is in my code (python) then it works fine.But as s...
Hi @Abhi0607 Can you please help me to find if you are taking or defining these parameter value outside try catch or inside it ?
I renamed our service principal in Terraform, which forces a replacement where the old service principal is removed and a new principal with the same permission is recreated. The Terraform succeeds to apply, but when I try to run dbt that creates tab...
This is also true for removing groups before unassigning them (removing and unassigning in Terraform)│ Error: cannot update grants: Could not find principal with name <My Group Name>
Hello Spark Community,I'm encountering an issue with parsing dates in a Spark DataFrame due to inconsistent date formats across my datasets. I need to identify and parse dates correctly, irrespective of their format. Below is a brief outline of my p...
How about not specifying the format? This will already match common formats.When you still have nulls, you can use your list with known exotic formats.Another solution is working with regular expressions. looking for 2 digit numbers not larger than...
Upon reading a CSV file with schema inference enabled, I've noticed that a column originally designated as string datatype contains numeric values with leading zeros. However, upon reading the data to Pyspark data frame, it undergoes automatic conver...
if you set .option("inferSchema", "false") all columns will be read as string.You will have to cast all the other columns to their appropriate type though. So passing a schema seems easier to me.
Hi!Started a job yesterday. It was iterating over data, 2-months at a time, and writing to a table. It was successfully doing this for 4 out of 6 time periods. The 5th time period however, got stuck, 5 hours in.I can find one Failed Stage that reads ...
As Spark is lazy evaluated, using only small clusters for read and large ones for writes is not something that will happen.The data is read when you apply an action (write f.e.).That being said: I have no knowledge of a bug in Databricks on clusters...
Hi everybody,I'm trying to setup a connection between Databricks' Notebooks and an external PostgreSQL database through a SSH-tunnel. On a single-node cluster, this is working perfectly fine. However, when this is ran on a multi-node cluster, this co...
I doubt it is possible.The driver runs the program, and sends tasks to the executors. But since creating the ssh tunnel is no spark task, I don't think it will be established on any executor.
Hi, I am using Azure databricks and we recently enabled UC in our workspace. We have some tables in our non UC metastore that we want to move to a UC enabled metastore. Is there any way we can move these tables without loosing the delta table history...
Hello,It is possible to have the expected result with dbutils.fs.cp("Origin location", "Destination location", True) and then create the table with the LOCATION of the Destination locationHope this helps
Running a single table is fast, but running 80 tables at the same time takes a long time, is it serial queued execution? Isn't it concurrent?

Can anyone explain in layman what is difference between Streaming and streaming live table ?
Streaming, in a broad sense, refers to the continuous flow of data over a network. It allows you to watch or listen to content in real-time without having to download the entire file first. A "Streaming Live Table" might refer to a specific type of ...
I am creating a data frame by reading a table's data residing in Azure backed unity catalog. I need to write the df or file to GCS bucket. I have configured the spark cluster config using the GCP service account json values.on running : df1.write.for...
Hi, is there any terraform resource to apply this GRANT or this have to be done always manually?
My job was not able to start because I got this problem in the job cluster.This job is running on a Azure Databricks workspace that has been deployed for almost a year and I have not had this error before. It is deployed in North Europe.After getting...
We have the same problem randomly occurring since yesterday in two workspaces.The cluster started fine today in the morning at 08:00, but failed again from around 09:00 on.
Hi,absolute Databricks noob here, but I'm trying to set up a DLT pipeline that processes cdc records from an external sql server instance to create a mirrored table in my databricks delta lakehouse. For this, I need to do some initial one-time backfi...
So since nobody responded, I decided to try my own suggestion and hack the snapshot data into the table that gathers the change data capture. After some straying I ended up with the notebook as attached.The notebook first creates 2 dlt tables (lookup...
