CDS 3 Powered by Apache Spark Requirements
The following sections describe software requirements for CDS 3 Powered by Apache Spark.
CDP Versions
Supported versions of CDP are described below.
| CDS Powered by Apache Spark Version | Supported CDP Versions |
|---|---|
| 3.0.1.3.0.7110.0-81 | CDP Private Cloud Base with Cloudera Runtime 7.1.3 and higher |
A Spark 2 service (included in CDP) can co-exist on the same cluster as Spark 3 (installed as a separate parcel). The two services are configured to not conflict, and both run on the same YARN service. Spark 3 installs and uses its own external shuffle service.
Although Spark 2 and Spark 3 can coexist in the same CDP Private Cloud Base cluster, you cannot use multiple Spark 3 versions simultaneously. All clusters managed by the same Cloudera Manager Server must use exactly the same version of CDS Powered by Apache Spark.
Scala Requirement
CDS 3 requires Scala 2.12.
Python Requirement
CDS 3 requires Python 3.4 or higher.
JDK Requirement
CDS 3 requires JDK 8 or JDK 11. Remove other JDK versions from all cluster and gateway hosts to ensure proper operation.
