Class JobId

java.lang.Object

com.spotify.helios.common.descriptors.Descriptor

com.spotify.helios.common.descriptors.JobId

All Implemented Interfaces:

Comparable<JobId>

public class JobId
extends Descriptor
implements Comparable<JobId>

Uniquely Identifies Jobs Has a string representation in JSON of:

 "name:version:hashvalue"
 

The hash value is so that if you are talking to multiple clusters, and the job definitions are slightly different, even though they have the same name and version, they will still be uniquely identifiable. This is most important when executing commands against multiple clusters. Many endpoints taking JobId can take an abbreviated JobId. That is, one without a the final colon and hash value.

Constructor Detail

JobId

public JobId(String name,
             String version,
             String hash)

Create a fully qualified job id with name, version and hash.

Parameters:

name - The name of the job.

version - The version of the job.

hash - The hash of the job.

JobId

public JobId(String name,
             String version)

Create a new job id with a specific name and version.

Parameters:

name - The name of the job.

version - the version of the job.

Method Detail

fromString

public static JobId fromString(String id)

Parse a job id string. This parsing method can be used when input is trusted, i.e. failing to parse it indicates programming error and not bad input.

Parameters:

id - A string representation of the job ID.

Returns:

The JobId object.

See Also:

parse(String)

parse

public static JobId parse(String id)
                   throws JobIdParseException

Parse a job id string. This parsing method can be used when input is not know to be correct. I.e. when parsing a job id supplied by the user in the cli or when parsing a request in the master rest interface.

Parameters:

id - A string representation of the job ID.

Returns:

The JobId object.

Throws:

JobIdParseException - If the ID cannot be parsed.
