The Jobs API allows you to define schedules for objects that perform work. You can schedule datasources, tasks, and Spark jobs. This topic explains how to format requests to the Jobs API. To learn how to work with jobs and schedules in the Fusion UI, see Jobs and Schedules.

​
Job runtime configuration

In order to see this object within the Fusion UI, it must be associated with an app. To do this, create the object using the /apps endpoint.
Job configuration requests have these parameters:
  • <type>:<id> path parameter (required)
    The resource identifier takes the form <type>:<id>, such as datasource:movie-db, spark:dailyMetricsRollup-counters, or task:delete-old-system-logs.
    See Job types below.
  • enabled body parameter
    ”True” or “false” to enable or disable the job.
  • triggers body parameter
    This parameter defines one or more conditions that trigger the job. See Job triggers below.
Below is an example request that configures a job: 
PUT /jobs/datasource:movie-db/schedule
{
  "enabled": true,
  "triggers": [
    {"type": "cron", "enabled": true, "value": "0 */10 * * * *"}
  ]
}

​
Job types

The job type must be specified as part of the resource identifier in PUT, POST, and DELETE calls. These are the possible job types:
datasourceA job to ingest data according to the specified datasource configuration, such as datasource:movie-db. Datasources are created using the Connector Datasources API or the Fusion UI. See Datasource Jobs.
sparkA Spark job to process data, such as spark:dailyMetricsRollup-counters. Spark jobs are created using the Spark Jobs API or the Fusion UI. See Spark Jobs.
taskA job to perform an HTTP call or log cleanup, such as task:delete-old-system-logs. Tasks are created using the Tasks API or the Fusion UI. See Tasks.

​
Job triggers

Each job can have multiple triggers, and each trigger configuration requires enabled and type parameters. Additional parameters are required by each trigger type, described below:
Trigger typeParameters
interval Run the job at a regular interval over some time range.

• startTime The date and time at which the job will first run, as an ISO-8601 date-time string.
• endTime The date and time at which the job will run last, as an ISO-8601 date-time string.
• interval The interval at which the job will run, as an integer whose unit is specified by repeatUnit below.
• repeatUnit One of: minute, hour, or day.

cron Run the job on a cron-style schedule.value A cron string.
job Run the job after another job succeeds or fails.

• jobID The ID of the job that triggers this one.
• runOnSuccess “True” to run when the specified job succeeds.
• runOnFailure “True” to run when the specified job fails.
• runOnAbort “True” to run when the specified job is aborted.

Examples

​
Get all datasource jobs

Input 
curl -u USERNAME:PASSWORD https://FUSION_HOST:8764/api/jobs?type=datasource
Output 
[ {
  "resource" : "datasource:ratings-db",
  "enabled" : true,
  "startedBy" : "acb38917-611a-46e1-a3cf-4ed46a30fd24"
}, {
  "resource" : "datasource:movies-db",
  "enabled" : true,
  "startedBy" : "acb38917-611a-46e1-a3cf-4ed46a30fd24",
  "status" : "success",
  "lastStartTime" : "2017-05-17T20:58:10.503Z",
  "lastEndTime" : "2017-05-17T20:58:42.020Z"
} ]

​
Start a datasource job now

Input 
curl -u USERNAME:PASSWORD -X POST -H "Content-Type: application/json" https://FUSION_HOST:8764/api/jobs/datasource:movies-db/actions -d '{"action": "start"}'
Output 
{
  "resource" : "datasource:movies-db",
  "action" : "start",
  "accepted" : true,
  "message" : "Started job datasource:movies-db"
}

​
Get the job history for a datasource

Input 
curl -u USERNAME:PASSWORD https://FUSION_HOST:8764/api/jobs/datasource:movies-db/history
Output 
[ {
  "resource" : "datasource:movies-db",
  "startTime" : "2017-05-17T21:01:46.743Z",
  "endTime" : "2017-05-17T21:02:05.720Z",
  "status" : "success"
}, {
  "resource" : "datasource:movies-db",
  "startTime" : "2017-05-17T20:58:10.503Z",
  "endTime" : "2017-05-17T20:58:42.020Z",
  "status" : "success"
} ]

​
Define a trigger for a datasource job

Input 
curl -u USERNAME:PASSWORD -X PUT -H "Content-Type: application/json" https://FUSION_HOST:8764/api/jobs/datasource:ratings-db/schedule -d '{"triggers": [{"type": "cron", "enabled": "true", "expression": "0 15 10 ? * MON-FRI"}]}'
Output 
{
  "resource" : "datasource:ratings-db",
  "triggers" : [ {
    "type" : "cron",
    "enabled" : true,
    "expression" : "0 15 10 ? * MON-FRI",
    "type" : "cron"
  } ]
}
