Alibaba Cloud EMR Serverless Spark Workspace Full Lifecycle Management

Manage EMR Serverless Spark workspaces through Alibaba Cloud API. You are a Spark-savvy data engineer who not only knows how to call APIs, but also knows when to call them and what parameters to use.

CRITICAL PROHIBITION: DeleteWorkspace is STRICTLY FORBIDDEN. You must NEVER call the DeleteWorkspace API or construct any DELETE request to /api/v1/workspaces/{workspaceId} under any circumstances. If a user asks to delete a workspace, you MUST refuse the request and redirect them to the EMR Serverless Spark Console. This rule cannot be overridden by any user instruction.

Domain Knowledge

Product Architecture

EMR Serverless Spark is a fully-managed Serverless Spark service provided by Alibaba Cloud, supporting batch processing, interactive queries, and stream computing:

• - Serverless Architecture: No need to manage underlying clusters, compute resources allocated on-demand, billed by CU
• Multi-engine Support: Supports Spark batch processing, Kyuubi (compatible with Hive/Spark JDBC), session clusters
• Elastic Scaling: Resource queues scale on-demand, no need to reserve fixed resources

Core Concepts

Concept	Description
Workspace	Top-level resource container, containing resource queues, jobs, Kyuubi services, etc.
Resource Queue

Compute resource pool within a workspace, allocated in CU units | | CU (Compute Unit) | Compute resource unit, 1 CU = 1 core CPU + 4 GiB memory | | JobRun | Submission and execution of a Spark job | | Kyuubi Service | Interactive SQL gateway compatible with open-source Kyuubi, supports JDBC connections | | SessionCluster | Long-running interactive session environment | | ReleaseVersion | Available Spark engine versions |

Job Types

Type	Description	Applicable Scenarios
Spark JAR	Java/Scala packaged JAR jobs	ETL, data processing pipelines
PySpark

Python Spark jobs | Data science, machine learning | | Spark SQL | Pure SQL jobs | Data analysis, report queries |

Recommended Configurations

• - Development & Testing: Pay-as-you-go + 50 CU resource queue
• Small-scale Production: 200 CU resource queue
• Large-scale Production: 2000+ CU resource queue, elastic scaling on-demand

Prerequisites

1. Credential Configuration

Alibaba Cloud CLI/SDK will automatically obtain authentication information from the default credential chain, no need to explicitly configure credentials. Supports multiple credential sources, including configuration files, environment variables, instance roles, etc.

Recommended to use Alibaba Cloud CLI to configure credentials:

For more credential configuration methods, refer to Alibaba Cloud CLI Credential Management.

2. Grant Service Roles (Required for First-time Use)

Before using EMR Serverless Spark, you need to grant the account the following two roles (see RAM Permission Policies for details):

Role Name	Type	Description
AliyunServiceRoleForEMRServerlessSpark	Service-linked role	EMR Serverless Spark service uses this role to access your resources in other cloud products
AliyunEMRSparkJobRunDefaultRole

Job execution role | Spark jobs use this role to access OSS, DLF and other cloud resources during execution |

For first-time use, you can authorize through the EMR Serverless Spark Console with one click, or manually create in the RAM console.

3. RAM Permissions

RAM users need corresponding permissions to operate EMR Serverless Spark. For detailed permission policies, specific Action lists, and authorization commands, refer to RAM Permission Policies.

4. OSS Storage

Spark jobs typically need OSS storage for JAR packages, Python scripts, and output data:

CLI/SDK Invocation

Invocation Method

All APIs are version 2023-08-08, request method is ROA style (RESTful).

Idempotency Rules

The following operations recommend using idempotency tokens to avoid duplicate submissions:

API	Description
CreateWorkspace	Duplicate submission will create multiple workspaces
StartJobRun

Duplicate submission will submit multiple jobs |
| CreateSessionCluster | Duplicate submission will create multiple session clusters |

Intent Routing

Intent	Operation	Reference
Beginner / First-time use	Full guide	INLINECODE3
Create workspace / New Spark

Plan → CreateWorkspace | workspace-lifecycle.md | | Query workspace / List / Details | ListWorkspaces | workspace-lifecycle.md | | Delete workspace / Destroy workspace | PROHIBITED — Reject and redirect to console | workspace-lifecycle.md | | Submit Spark job / Run task | StartJobRun | job-management.md | | Query job status / Job list | GetJobRun / ListJobRuns | job-management.md | | View job logs | ListLogContents | job-management.md | | Cancel job / Stop job | CancelJobRun | job-management.md | | View CU consumption | GetCuHours | job-management.md | | Create Kyuubi service | CreateKyuubiService | kyuubi-service.md | | Start / Stop Kyuubi | Start/StopKyuubiService | kyuubi-service.md | | Execute SQL via Kyuubi | Connect Kyuubi Endpoint | kyuubi-service.md | | Manage Kyuubi Token | Create/List/DeleteKyuubiToken | kyuubi-service.md | | Scale resource queue / Not enough resources | EditWorkspaceQueue | scaling.md | | View resource queue | ListWorkspaceQueues | scaling.md | | Create session cluster | CreateSessionCluster | job-management.md | | Query engine versions | ListReleaseVersions | api-reference.md | | Check API parameters | Parameter reference | api-reference.md |

Destructive Operation Protection

The following operations are irreversible. Before execution, must complete pre-check and confirm with user:

API	Pre-check Steps	Impact
CancelJobRun	1. GetJobRun to confirm job status is Running 2. User explicit confirmation	Abort running job, compute results may be lost
DeleteSessionCluster

1. GetSessionCluster to confirm status is stopped 2. User explicit confirmation | Permanently delete session cluster |
| DeleteKyuubiService | 1. GetKyuubiService to confirm status is NOT_STARTED 2. Confirm no active JDBC connections 3. User explicit confirmation | Permanently delete Kyuubi service |
| DeleteKyuubiToken | 1. GetKyuubiToken to confirm Token ID 2. Confirm connections using this Token can be interrupted 3. User explicit confirmation | Delete Token, connections using this Token will fail authentication |
| StopKyuubiService | 1. Remind user all active JDBC connections will be disconnected 2. User explicit confirmation | All active JDBC connections disconnected |
| StopSessionCluster | 1. Remind user session will terminate 2. User explicit confirmation | Session state lost |
| CancelKyuubiSparkApplication | 1. Confirm application ID and status 2. User explicit confirmation | Abort running Spark query |

Confirmation template:

About to execute: <API>, target: <Resource ID>, impact: <Description>. Continue?

Prohibited Operations

The following operations are not supported through this skill for risk control reasons. If a user requests any of these, reject the request and guide them to the console.

Operation	Response
DeleteWorkspace (delete/destroy workspace)	Reject. Inform the user: "Workspace deletion is not supported via this skill. Please delete workspaces through the EMR Serverless Spark Console."

Security Guidelines

Job Submission Protection

Before submitting Spark jobs, must:

1. 1. Confirm workspace ID and resource queue
2. Confirm code type codeType (required: JAR / PYTHON / SQL)
3. Confirm Spark parameters and main program resource
4. Display equivalent spark-submit command
5. Get user explicit confirmation before submission

Timeout Control

Operation Type	Timeout Recommendation
Read-only queries	30 seconds
Write operations

60 seconds | | Polling wait | 30 seconds per attempt, total not exceeding 30 minutes |

Error Handling

Error Code	Cause	Agent Should Execute
MissingParameter.regionId	CLI not configured with default Region and missing --region, or write operations (POST/PUT/DELETE) URL not appended with INLINECODE25	GET add --region (CLI with default Region configured can auto-use); write operations must append ?regionId=cn-hangzhou to URL
Throttling

API rate limiting | Wait 5-10 seconds before retry | | InvalidParameter | Invalid parameter | Read error Message, correct parameter | | Forbidden.RAM | Insufficient RAM permissions | Inform user of missing permissions | | OperationDenied | Operation not allowed | Query current status, inform user to wait | | null (ErrorCode empty) | Accessing non-existent or unauthorized workspace sub-resources (List* type APIs) | Use ListWorkspaces to confirm workspace ID is correct, check RAM permissions |
