There are two types of auto scaling in Databricks: Standard and Optimized. In both scenarios when tasks are submitted the cluster will begin scaling to execute as many of them in parallel immediately.Scaling down is different. In optimized autoscalin...
Yes, you can alerts - Email alerts sent in case of job failure, success, or timeout. You can set alerts up for job start, job success, and job failure (including skipped jobs), providing multiple comma-separated email addresses for each alert type. Y...
Are there recommendations and/or examples of leveraging AWS and Azure with Databricks? If so, is there any best practices to follow? Want to ensure we avoid expensive data transfer across clouds
I imported one workspace into another and noticed there were several instances of RESOURCE_DOES_NOT_EXIST errors because of the folder structure of the workspace (despite importing the workspace as well), see example below:Get: https://dbc-9d482d3a-f...

Is there an easy way I can save the plots generated by the display() cmd?
Plots generated via the display() command are automatically saved under /FileStore/plots. See the documentation for more info: https://docs.databricks.com/data/filestore.html#filestore.However, perhaps an easier approach to save/revisit plots is to u...
If you are talking about distributed training of a single XGBoost model, there is no built-in capability in SparkML. SparkML supports gradient boosted trees, but not XGBoost specifically. However, there are 3rd party packages, such as XGBoost4J that ...
With Spark, there are a few ways you can scale your model: TrainingHyperparameter tuningInferenceIf you're looking to train one model across multiple workers, you can leverage Horovod. It's an open source project designed to simplify distributed neur...
Right after I install a library in my cluster, my cluster goes unresponsive and nothing runs. How to solve this issue?
it is a standard cluster. It is happening for all libraries. is there a way to debug or show the errors messages if any?
Pandas works for single machine computations, so any pandas code you write on Databricks will run on the driver of the cluster. Pyspark and Koalas are both distributed frameworks for when you have large datasets. You can use Pyspark and Koalas inte...
I want to know how to use Hyperopt in different situations:Tuning a single-machine algorithm from scikit-learn or single-node TensorFlowTuning a distributed algorithm from Spark ML or distributed TensorFlow / Horovod
The right question to ask is indeed: Is the algorithm you want to tune single-machine or distributed?If it's a single-machine algorithm like any from scikit-learn, then you can use SparkTrials with Hyperopt to distribute hyperparameter tuning.If it's...
Both the following commands fail df1 = sqlContext.read.format("xml").load(loadPath) df2 = sqlContext.read.format("com.databricks.spark.xml").load(loadPath) with the following error message: java.lang.ClassNotFoundException: Failed to find data sour...
Hi, If you are getting this error is due com.sun.xml.bind library is obsolete now. You need to download org.jvnet.jaxb2.maven package into a library by using Maven Central and attach that into a cluster. Then you are going to be able to use xml...
Yes, you can use the widgets api to have some control to validate the input before you pass the values to the rest of your codeFor example:folder = dbutils.widgets.get("Folder") if folder == "": raise Exception("Folder missing")or to get spark se...
