I keep it a point to use the latest DBR versions for my workloads and mostly we leverage those new features. But I have 300 jobs on the Databricks workspace and updating the DBR versions for each job manually is difficult to do. Any quick hack
Below code snippet can be helpful if you are using Databricks CLIfor jobid in `databricks jobs list | awk '{print $1}'`; do databricks jobs get --job-id $jobid | jq .settings > /tmp/jobs/$jobid.json; done sed -i 's/"spark_version": ".*"/"spark_ver...
I do not want to upgrade my cluster every one month. I am looking for stability over new features.
The strong recommendation is not to use an unsupported version of DBR on your cluster. For production workloads where you don't welcome newer versions, then check the Databricks LTS DBR versions. if using an unsupported version then you don't receiv...
I am reading data from S3 from a Databricks cluster and the read operation seldom fails with 403 permission errors. Restarting the cluster fixes my issue.
The main reason for this behavior is : AWS keys are used in addition to the IAM role. Using global init scripts to set the AWS keys can cause this behavior.The IAM role has the required permission to access the S3 data, but AWS keys are set in the Sp...

Currently, Table ACL does not support column-level security. There are several tools like Privcera which has better integration with Databricks.
I've seen .cache() and .checkpoint() used similarly in some workflows I've come across. What's the difference, and when should I use one over the other?
Caching is extremely useful than checkpointing when you have lot of available memory to store your RDD or Dataframes if they are massive.Caching will maintain the result of your transformations so that those transformations will not have to be recomp...
1. We want a venue in which we can rapidly iterate and make new releases. The overhead of making a release as a separate project is minuscule (in the order of minutes). A release on Spark takes a lot longer (in the order of days)2. Koalas takes a dif...
Different projects have different focuses. Spark is already deployed in virtually every organization, and often is the primary interface to the massive amount of data stored in data lakes. Koalas was inspired by Dask, and aims to make the transition ...
