Method Detail

resolveJob

@Nonnull
 @Transactional
public ResolvedJob resolveJob(java.lang.String id)
                                                throws com.netflix.genie.common.internal.exceptions.checked.GenieJobResolutionException,
                                                       com.netflix.genie.common.internal.exceptions.unchecked.GenieJobResolutionRuntimeException

Given the id of a job that was successfully submitted to the system this API will attempt to resolve all the concrete details (cluster, command, resources, etc) needed for the system to actually launch the job. Once these details are determined they are persisted and the job is marked as JobStatus.RESOLVED.

Specified by:

resolveJob in interface JobResolverService

Parameters:

id - The id of the job to resolve. The job must exist and its status must return true from JobStatus.isResolvable()

Returns:

A ResolvedJob instance containing all the concrete information needed to execute the job

Throws:

com.netflix.genie.common.internal.exceptions.checked.GenieJobResolutionException - When the job cannot resolved due to unsatisfiable constraints

com.netflix.genie.common.internal.exceptions.unchecked.GenieJobResolutionRuntimeException - When the job fails to resolve due to a runtime error.

resolveJob

public ResolvedJob resolveJob(java.lang.String id,
                                       @Valid

Parameters:

id - The id of the job

jobRequest - The job request containing all details a user wants to have for their job

apiJob - true if this job was submitted via the REST API. false otherwise.

Returns:

The completely resolved job information within a ResolvedJob instance

Throws:

com.netflix.genie.common.internal.exceptions.checked.GenieJobResolutionException - When the job cannot resolved due to unsatisfiable constraints

com.netflix.genie.common.internal.exceptions.unchecked.GenieJobResolutionRuntimeException - When the job fails to resolve due to a runtime error.
