Ensure TDSQL Component Versions Are Consistent Across the Cluster

How it is checked

Audit method: Manual review

This recommendation cannot be checked automatically. A scan lists it with these instructions when you pass --include-manual.

On every node run <tdsql>/bin/oss_server --version and <tdsql>/bin/scheduler --version, or call the OSS TDSQL.GetDbVersion / TDSQL.TdsqlModuleVersion interfaces for the cluster, and compare the results. All OSS, Scheduler/Keeper, Agent, Gateway and data-node versions must match across the cluster; a mismatch outside a planned rolling upgrade is a finding.

How it is fixed

Fix method: Guidance or infrastructure patch

Plan and execute a rolling upgrade to ensure version consistency. Follow the TDSQL upgrade documentation.
