Huawei SubmitJob

Huawei SubmitJob
Certified
Submit a job step to an existing Huawei Cloud MRS cluster

Submits a single job execution to an already-running MRS cluster via createExecuteJob — the Huawei Cloud equivalent of io.kestra.plugin.aws.emr.SubmitSteps, adapted to MRS's one-job-per-call submission API.

Set wait to true (the default) to poll the job until it reaches a terminal state (FINISHED, or a failure state), or false to fire-and-forget and return immediately after submission.

yaml
type: io.kestra.plugin.huawei.mrs.SubmitJob

Examples

Submit a Hive script to a running cluster and wait for it to finish.

yaml
id: mrs_submit_job
namespace: company.team

tasks:
  - id: submit_job
    type: io.kestra.plugin.huawei.mrs.SubmitJob
    accessKeyId: "{{ secret('HUAWEI_AK') }}"
    secretAccessKey: "{{ secret('HUAWEI_SK') }}"
    region: eu-west-101
    projectId: "{{ secret('HUAWEI_PROJECT_ID') }}"
    clusterId: "{{ outputs.create_cluster.clusterId }}"
    job:
      jobType: HIVE_SCRIPT
      jobName: cleanup-staging
      arguments:
        - "obs://my-bucket/scripts/cleanup.sql"
    maxDuration: PT20M

Properties

clusterId *string

ID of the target cluster

The cluster must already exist and be in the running state.

job *string

Job step to submit

Definitions

io.kestra.plugin.huawei.mrs.models.JobConfig

jobName*string

Job name

A unique, human-readable name for this job step within the cluster.

jobType*string

Possible Values

MAP_REDUCESPARK_SUBMITHIVE_SCRIPTHIVE_SQLDIST_CPSPARK_SCRIPTSPARK_SQLFLINK

Job execution type

argumentsarray

SubTypestring

Job arguments

Positional arguments passed to the job, e.g. the main class, jar path, or script arguments.

propertiesobject

Extra job configuration entries

Key/value pairs forwarded as-is to the job's properties field.

accessKeyId string

Access Key (AK) used to authenticate with Huawei Cloud

Huawei Cloud access key used together with secretAccessKey to sign API requests. Required for AK/SK-based authentication; not required when providing a pre-obtained securityToken. Sensitive — always provide via {{ secret('NAME') }}.

domainId string

Huawei Cloud Account Domain ID

Identifies the Huawei Cloud account (domain). Required when authenticating against global services such as IAM, or when requesting a domain-scoped IAM token.

endpointOverride string

MRS endpoint URL override

Overrides the default endpoint derived from region and endpointSuffix. Use this for private endpoints, non-standard deployments, or tests. When set, endpointSuffix is ignored.

Format: https://mrs.<region>.myhuaweicloud.com (without trailing slash).

endpointSuffix string

Huawei Cloud domain suffix

Controls the top-level domain used when deriving the MRS endpoint from region. Defaults to myhuaweicloud.com. Set to myhuaweicloud.eu for the Huawei Cloud European sovereign cloud.

Ignored when endpointOverride is set.

interval string

DefaultPT5S

Polling interval while waiting for the job

ISO-8601 duration. Defaults to 5 seconds.

maxDuration string

DefaultPT1H

Maximum time to wait for the job to complete

ISO-8601 duration. Defaults to 1 hour.

pluginDefaultsRef string

Reference (ref) of the pluginDefaults to apply to this task.

projectId string

Huawei Cloud Project ID

Identifies the region-scoped project against which most regional services authenticate. Mutually exclusive with domainId for global services such as IAM.

region string

Huawei Cloud region

Region identifier such as eu-west-101, ap-southeast-1, or cn-north-4.

secretAccessKey string

Secret Key (SK) used to authenticate with Huawei Cloud

Huawei Cloud secret key paired with accessKeyId. Required for AK/SK-based authentication. Sensitive — always provide via {{ secret('NAME') }}.

securityToken string

Pre-obtained Huawei Cloud IAM token used as bearer credential for downstream API calls

When set, downstream Huawei tasks send this value in the X-Auth-Token header instead of signing requests with AK/SK. Sensitive.

temporaryCredentials string

Inline IAM credential exchange

When set, the connection layer calls the Huawei IAM STS API once per task execution and uses the returned temporary AK/SK + security token instead of the static accessKeyId and secretAccessKey properties.

Configure once via pluginDefaults to apply transparently to every task in a namespace without per-task credential wiring:

pluginDefaults: 
  - type: io.kestra.plugin.huawei.obs
    values: 
      region: eu-west-101
      temporaryCredentials: 
        authMethod: PASSWORD
        username: my-iam-user
        password: "{{ secret('HUAWEI_IAM_PASSWORD') }}"
        domainName: my-account-domain
        durationSeconds: 3600

**Long-running tasks: ** the exchange runs once at execution start. For RealtimeTrigger or long-running Consume tasks that outlive durationSeconds, credentials will expire mid-run. Use long-lived AK/SK properties or refresh externally in that case.

Definitions

io.kestra.plugin.huawei.TemporaryCredentialsConfig

authMethodstring

DefaultPASSWORD

Possible Values

PASSWORDTOKEN

Authentication method

Controls which credentials are used to obtain the session token before exchanging for temporary STS credentials.

PASSWORD (default): provide username, password, and domainName.
TOKEN: provide an existing iamToken (X-Auth-Token).

domainNamestring

Account domain name (PASSWORD method only)

The Huawei Cloud account name (domain name) that owns the IAM user. Required when authMethod is PASSWORD. Visible in the Huawei Cloud console under My Credentials → Domain Name.

durationSecondsintegerstring

Default900

Lifetime of the temporary credentials in seconds

How long the returned temporary AK/SK/security-token should remain valid. Huawei Cloud accepts values between 900 (15 minutes) and 86400 (24 hours). Defaults to 900 seconds.

endpointSuffixstring

Defaultmyhuaweicloud.com

Huawei Cloud IAM endpoint suffix

Domain suffix used to build the IAM endpoint URL when no explicit endpoint override is set. Defaults to myhuaweicloud.com. Set to myhuaweicloud.eu for the European sovereign cloud (region eu-west-101 / EU-Dublin).

iamTokenstring

IAM token to exchange (TOKEN method only)

An existing Huawei Cloud X-Auth-Token to exchange for temporary STS credentials. Required when authMethod is TOKEN. Sensitive — always provide via {{ secret('NAME') }}.

passwordstring

IAM password (PASSWORD method only)

Password for the IAM user identified by username. Required when authMethod is PASSWORD. Sensitive — always provide via {{ secret('NAME') }}.

projectNamestring

Project name for project-scoped tokens (PASSWORD method only)

Overrides the project name used for scope=PROJECT token requests. Defaults to the task's region value when omitted, which is correct for most regions.

scopestring

DefaultPROJECT

Possible Values

PROJECTDOMAIN

Token scope (PASSWORD method only)

Scope of the session token obtained during password authentication.

PROJECT (default): token is scoped to the project matching projectName (or the task's region when projectName is omitted). Use for most downstream tasks.
DOMAIN: token is scoped to the domain.
