Databricks Runtime 7.0 (unsupported)

  • Article

Databricks released this image in June 2020.

The following release notes provide information about Databricks Runtime 7.0, powered by Apache Spark 3.0.

New features

Databricks Runtime 7.0 includes the following new features:

  • Scala 2.12

    Databricks Runtime 7.0 upgrades Scala from 2.11.12 to 2.12.10. The change list between Scala 2.12 and 2.11 is in the Scala 2.12.0 release notes.

  • Auto Loader (Public Preview), released in Databricks Runtime 6.4, has been improved in Databricks Runtime 7.0

    Auto Loader gives you a more efficient way to process new data files incrementally as they arrive on a cloud blob store during ETL. This is an improvement over file-based structured streaming, which identifies new files by repeatedly listing the cloud directory and tracking the files that have been seen, and can be very inefficient as the directory grows. Auto Loader is also more convenient and effective than file-notification-based structured streaming, which requires that you manually configure file-notification services on the cloud and doesn't let you backfill existing files. For details, see What is Auto Loader?.

    On Databricks Runtime 7.0 you no longer need to request a custom Databricks Runtime image in order to use Auto Loader.

  • COPY INTO (Public Preview), which lets you load data into Delta Lake with idempotent retries, has been improved in Databricks Runtime 7.0

    Released as a Public Preview in Databricks Runtime 6.4, the COPY INTO SQL command lets you load data into Delta Lake with idempotent retries. To load data into Delta Lake today you have to use Apache Spark DataFrame APIs. If there are failures during loads, you have to handle them effectively. The new COPY INTO command provides a familiar declarative interface to load data in SQL. The command keeps track of previously loaded files and you safely re-run it in case of failures. For details, see COPY INTO.

Improvements

  • Azure Synapse (formerly SQL Data Warehouse) connector supports the COPY statement.

    The main benefit of COPY is that lower privileged users can write data to Azure Synapse without needing strict CONTROL permissions on Azure Synapse.

  • The %matplotlib inline magic command is no longer required to display Matplolib objects inline in notebook cells. They are always displayed inline by default.

  • Matplolib figures are now rendered with transparent=False, so that user-specified backgrounds are not lost. This behavior can be overridden by setting Spark configuration spark.databricks.workspace.matplotlib.transparent true.

  • When running Structured Streaming production jobs on High Concurrency mode clusters, restarts of a job would occasionally fail, because the previously running job wasn't terminated properly. Databricks Runtime 6.3 introduced the ability to set the SQL configuration spark.sql.streaming.stopActiveRunOnRestart true on your cluster to ensure that the previous run stops. This configuration is set by default in Databricks Runtime 7.0.

Major library changes

Python packages

Major Python packages upgraded:

  • boto3 1.9.162 -> 1.12.0
  • matplotlib 3.0.3 -> 3.1.3
  • numpy 1.16.2 -> 1.18.1

Java and Scala libraries

  • Apache Hive version used for handling Hive user-defined functions and Hive SerDes upgraded to 2.3.
  • Previously Azure Storage and Key Vault jars were packaged as part of Databricks Runtime, which would prevent you from using different versions of those libraries attached to clusters. Classes under com.microsoft.azure.storage and com.microsoft.azure.keyvault are no longer on the class path in Databricks Runtime. If you depend on either of those class paths, you must now attach Microsoft Azure Storage SDK or Azure Key Vault SDK to your clusters.

Behavior changes

This section lists behavior changes from Databricks Runtime 6.6 to Databricks Runtime 7.0. You should be aware of these as you migrate workloads from lower Databricks Runtime releases to Databricks Runtime 7.0 and above.

Spark behavior changes

Because Databricks Runtime 7.0 is the first Databricks Runtime built on Spark 3.0, there are many changes that you should be aware of when you migrate workloads from Databricks Runtime 5.5 LTS or 6.x, which are built on Spark 2.4. These changes are listed in the "Behavior changes" section of each functional area in the Apache Spark section of this release notes article:

Other behavior changes

  • The upgrade to Scala 2.12 involves the following changes:

    • Package cell serialization is handled differently. The following example illustrates the behavior change and how to handle it.

      Running foo.bar.MyObjectInPackageCell.run() as defined in the following package cell will trigger the error java.lang.NoClassDefFoundError: Could not initialize class foo.bar.MyObjectInPackageCell$

      package foo.bar

case class MyIntStruct(int: Int)

import org.apache.spark.sql.SparkSession
import org.apache.spark.sql.functions._
import org.apache.spark.sql.Column

object MyObjectInPackageCell extends Serializable {

  // Because SparkSession cannot be created in Spark executors,
  // the following line triggers the error
  // Could not initialize class foo.bar.MyObjectInPackageCell$
  val spark = SparkSession.builder.getOrCreate()

  def foo: Int => Option[MyIntStruct] = (x: Int) => Some(MyIntStruct(100))

  val theUDF = udf(foo)

  val df = {
    val myUDFInstance = theUDF(col("id"))
    spark.range(0, 1, 1, 1).withColumn("u", myUDFInstance)
  }

  def run(): Unit = {
    df.collect().foreach(println)
  }
}

      To work around this error, you can wrap MyObjectInPackageCell inside a serializable class.

    • Certain cases using DataStreamWriter.foreachBatch will require a source code update. This change is due to the fact that Scala 2.12 has automatic conversion from lambda expressions to SAM types and can cause ambiguity.

      For example, the following Scala code can't compile:

      streams
  .writeStream
  .foreachBatch { (df, id) => myFunc(df, id) }

      To fix the compilation error, change foreachBatch { (df, id) => myFunc(df, id) } to foreachBatch(myFunc _) or use the Java API explicitly: foreachBatch(new VoidFunction2 ...).

  • Because the Apache Hive version used for handling Hive user-defined functions and Hive SerDes is upgraded to 2.3, two changes are required:

    • Hive's SerDe interface is replaced by an abstract class AbstractSerDe. For any custom Hive SerDe implementation, migrating to AbstractSerDe is required.
    • Setting spark.sql.hive.metastore.jars to builtin means that the Hive 2.3 metastore client will be used to access metastores for Databricks Runtime 7.0. If you need to access Hive 1.2 based external metastores, set spark.sql.hive.metastore.jars to the folder that contains Hive 1.2 jars.

Deprecations and removals

  • Data skipping index was deprecated in Databricks Runtime 4.3 and removed in Databricks Runtime 7.0. We recommend that you use Delta tables instead, which offer improved data skipping capabilities.
  • In Databricks Runtime 7.0, the underlying version of Apache Spark uses Scala 2.12. Since libraries compiled against Scala 2.11 can disable Databricks Runtime 7.0 clusters in unexpected ways, clusters running Databricks Runtime 7.0 and above do not install libraries configured to be installed on all clusters. The cluster Libraries tab shows a status Skipped and a deprecation message that explains the changes in library handling. However, if you have a cluster that was created on an earlier version of Databricks Runtime before Azure Databricks platform version 3.20 was released to your workspace, and you now edit that cluster to use Databricks Runtime 7.0, any libraries that were configured to be installed on all clusters will be installed on that cluster. In this case, any incompatible JARs in the installed libraries can cause the cluster to be disabled. The workaround is either to clone the cluster or to create a new cluster.

Behavior changes for Spark core, Spark SQL, and Structured Streaming

The following migration guides list behavior changes between Apache Spark 2.4 and 3.0. These changes may require updates to jobs that you have been running on lower Databricks Runtime versions:

The following behavior changes are not covered in these migration guides:

  • In Spark 3.0, the deprecated class org.apache.spark.sql.streaming.ProcessingTime has been removed. Use org.apache.spark.sql.streaming.Trigger.ProcessingTime instead. Likewise, org.apache.spark.sql.execution.streaming.continuous.ContinuousTrigger has been removed in favor of Trigger.Continuous, and org.apache.spark.sql.execution.streaming.OneTimeTrigger has been hidden in favor of Trigger.Once. (SPARK-28199)
  • In Databricks Runtime 7.0, when reading a Hive SerDe table, by default Spark disallows reading files under a subdirectory that is not a table partition. To enable it, set the configuration spark.databricks.io.hive.scanNonpartitionedDirectory.enabled as true. This does not affect Spark native table readers and file readers.

The following behavior changes are not covered in the migration guide:

  • In Spark 3.0, a multiclass logistic regression in Pyspark will now (correctly) return LogisticRegressionSummary, not the subclass BinaryLogisticRegressionSummary. The additional methods exposed by BinaryLogisticRegressionSummary would not work in this case anyway. (SPARK-31681)
  •  In Spark 3.0, pyspark.ml.param.shared.Has* mixins do not provide any set*(self, value) setter methods anymore, use the respective self.set(self.*, value) instead. See SPARK-29093 for details. (SPARK-29093)

Deprecations

Known issues

  • Parsing day of year using pattern letter 'D' returns the wrong result if the year field is missing. This can happen in SQL functions like to_timestamp which parses datetime string to datetime values using a pattern string. (SPARK-31939)
  • Join/Window/Aggregate inside subqueries may lead to wrong results if the keys have values -0.0 and 0.0. (SPARK-31958)
  • A window query may fail with ambiguous self-join error unexpectedly. (SPARK-31956)
  • Streaming queries with dropDuplicates operator may not be able to restart with the checkpoint written by Spark 2.x. (SPARK-31990)
