Huawei Cloud MRS cluster fault diagnosis skill. Diagnoses service faults, instance faults, and host faults through progressive root cause localization: quick log scan first, host troubleshooting when host issues are found, detailed investigation when no conclusion is reached. Diagnosis is driven by the built-in LakeWatch API client (lakewatch mode) or the MRS Manager API client (manager mode) and the per-layer knowledge base under fault_layer/ and scenarios/ (lakewatch) or fault_layer_manager/…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Huawei Cloud MRS Host Fault Diagnosis Skill ## Overview This skill diagnoses Huawei Cloud MRS (MapReduce Service) cluster faults. Given a service name and/or node name, it progressively localizes the root cause: quick log scan first, host troubleshooting when host issues are found, detailed investigation when no conclusion is reached. **Architecture**: Caller (Agent) -> `check_api_mode.py` (Python, scripts/) determines the API mode -> either `lakewatch_api_client.py` -> LakeWatch API -> MRS cluster (node resource data, logs, MRS Manager proxy) or `manager_api_client.py` -> MRS Manager REST API (28443). Per-layer knowledge base (`fault_layer/` + `scenarios/` + `propagation.md` in lakewatch mode; `fault_layer_manager/` + `scenarios_manager/` + `propagation_manager.md` in manager mode) drives the diagnosis flow; per-component config under `components/` is shared by both modes; three fault layers (host -> instance -> service) with propagation chain tracing. …

How to install
mdr add huaweicloud/huaweicloud-skills/huawei-cloud-mrs-host-fault-diagnose@sha256:5879850b426acbf9The line at the top of this page pins the label git:20260921.00441bc, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
