MRS Cluster Version Lifecycle

Version Description

MRS allows you to create clusters of two editions: normal and LTS.

  • Version number of the normal edition: The format is a.b.c.d.

    a.b indicates the major version, c indicates the minor version, and d indicates the patch version. For example, MRS 3.1.5.1.

    • a indicates great changes among major versions.
    • b indicates component changes.
    • c indicates minor changes, which are forward compatible.
    • d indicates the patch version, which is used to rectify faults.
    Figure 1 MRS normal cluster version

  • Version number of the LTS edition: The format is a.b.c-LTS.d.

    a.b indicates the major version, c indicates the minor version, and d indicates the patch version. For example, MRS 3.2.0-LTS.1.

    • a indicates great changes among major versions.
    • b indicates component changes.
    • c indicates minor changes, which are forward compatible.
    • d indicates the patch version, which is used to rectify faults.

Version Support

  • Cluster creation

    MRS allows you to create two major versions of the same edition.

    For example, you can create clusters of MRS 3.3.0-LTS and MRS 3.2.0-LTS. After MRS 3.3.0-LTS is available for commercial use, clusters of MRS 3.1.x-LTS and earlier versions cannot be created on the console by default. Created MRS 3.1.2-LTS clusters are not affected.

  • Cluster version upgrade

    The MRS LTS edition supports major version upgrade. By default, only one-major-version upgrade is supported. For example, MRS 3.1.2-LTS can be upgraded to MRS 3.2.0-LTS, and MRS 3.2.0-LTS can be upgraded to MRS 3.3.0-LTS.

  • Cluster patch upgrade

    If MRS clusters running on the live network have major issues or vulnerabilities in the open-source big data components, you can install patches for these clusters. For details, see MRS Patch Description.

Version Constraints

  • After a cluster is upgraded, it cannot be rolled back to an earlier version.
  • Clusters of the normal edition cannot be upgraded.

Version Release Cycle/Version Lifecycle

Table 1 Common terms about version lifecycle

Term

Definition

End of marketing (EOM)

The deployment of a cloud service version is stopped and the cloud service version is no longer deployed on the live network.

End of Full Support (EOFS)

The fixing of common software bugs in a specified cloud service version stops. The support covers only the fixing of mission-critical issues and security issues and the necessary upgrades.

End of Service (EOS)

The cloud service version is no longer used. The live network version needs to be upgraded to the latest cloud service version.

For a newly released MRS version, the EOM date is two years later, the EOFS date is one year after EOM, and the EOS date is half a year after EOFS.

For example, if MRS 3.3.1-LTS is released on March 30, 2024, its EOM date is March 30, 2026, EOFS date is March 30, 2027, and EOS date is September 30, 2027.

Remarks

The EOS date of historical versions is earlier than August 30, 2024. Versions that have reached their EOS dates will still be provided until August 30, 2024. That is, these versions will not be available after August 30, 2024.

Recommended Action After Version EOX

  • Version upgrade: The MRS LTS edition supports in-place version upgrade. You can perform an upgrade based on the specific version upgrade path.
  • Cluster migration: The MRS normal edition does not support in-place upgrade. You need to migrate clusters to the latest version.
