Overview

For greenfield MRS cluster scenarios, derives YARN vCPU/memory and storage requirements through business investigation (components, daily incremental data, compute window, concurrency, throughput), evaluates Master and Core node specs and quantities, and outputs a minimum-redundancy spec plan that fits business requirements. Key difference from the migration scenario skill (huawei-cloud-mrs-migration-planner): no existing cluster resource benchmark; resource targets are derived from business load models.

Security rule: Resource estimation coefficients are industry experience-based estimates and must be annotated as "estimated value" in the report. The report script only takes business data via --input/stdin and generates the Excel file locally — it accepts no arbitrary shell arguments, performs no shell execution, and makes no cloud resource write operations.

Prerequisites

• Python3 + openpyxl (pip install openpyxl) — for generating multi-sheet Excel report
• Deployment region defaults to cn-north-4 (widest flavor availability); no need to ask user. If user explicitly specifies another region, verify aC9 and other series availability in that region before sizing
