HOW TO - Check the DSE version running on a node

Overview

This article discusses the various options available for checking running versions of DataStax Enterprise on a node.

Procedure

OPTION 1 - Use the dse command

Specify the -v (version) flag with the command.

Here are example outputs:

$ dse -v
6.7.3

$ dse -v
6.0.8

$ dse -v
5.1.14

OPTION 2 - Use the nodetool utility

Run the nodetool version command to get the version of the database included in DSE.

Here are example outputs for different DSE versions:

$ nodetool version
ReleaseVersion: 3.11.3.5115

$ nodetool version
ReleaseVersion: 4.0.0.608

$ nodetool version
DSE version: 6.7.3
ReleaseVersion: 4.0.0.673

Version numbering 

Apache Cassandra versions have the form X.Y.Z where:

• X is the major version
• Y is the minor version
• Z is the patch version

This scheme more or less follows Tom Preston-Werner's Semantic Versioning specification.

The database included in DataStax Enterprise expands on the versioning scheme with the addition of a DSE-specific version. For example, DSE 5.1.10 included Apache Cassandra™ 3.11.0.2323 which means that the database was built on top of Cassandra 3.11.0 plus additional DSE enhancements version 2323.

From DSE 5.0.15, DSE 5.1.11, DSE 6.0.3 and DSE 6.7.0, the database version reported is simplified to match the DSE version (DB-1699). Using the examples above:

• ReleaseVersion: 3.11.3.5115 is the database version for DSE 5.1.15 (5115)
• ReleaseVersion: 4.0.0.608 indicates that the DSE 6.0.8 database is compatible with Apache Cassandra 4.0.0
