How to Use

Click EMR AI Assistant in the application sidebar.

Enter keywords or questions in the conversation window.

Intelligent Conversation

The assistant can answer comprehensive EMR knowledge, understand natural‑language queries, and handle complex problems.

Examples

How to configure auto‑scaling for a cluster?

List EMR clusters under my account.

Check if cluster services are normal.

How to modify service configuration?

For example, typing “How to configure auto‑scaling for the cluster” will display detailed guidance.

Anomaly Diagnosis

The assistant can diagnose open‑source component issues, analyze error messages from cluster operations, and monitor real‑time metrics to provide troubleshooting steps.

Examples

Zookeeper status abnormal – how to handle?

Node memory usage abnormal – how to resolve?

Entering “Zookeeper status abnormal – how to handle?” will show troubleshooting suggestions.

Operation Invocation

Supported operations include modifying component configuration, cluster scaling, updating bootstrap scripts, viewing resource lists, and checking operation history.

Example

Typing “Cluster scaling Task node” will display an operation card for scaling after user confirmation.
