A configurable parameter that replaces one or more fields in the template. Parameterizable fields:

• Labels
• File uris
• Job properties
• Job arguments
• Script variables
• Main class (in HadoopJob and SparkJob)
• Zone (in ClusterSelector)

Methods

#description

def description() -> ::String

Returns

• (::String) — Optional. Brief description of the parameter. Must not exceed 1024 characters.

#description=

def description=(value) -> ::String

Parameter

• value (::String) — Optional. Brief description of the parameter. Must not exceed 1024 characters.

Returns

• (::String) — Optional. Brief description of the parameter. Must not exceed 1024 characters.

#fields

def fields() -> ::Array<::String>

Returns

• (::Array<::String>) —

  Required. Paths to all fields that the parameter replaces. A field is allowed to appear in at most one parameter's list of field paths.

  A field path is similar in syntax to a google.protobuf.FieldMask. For example, a field path that references the zone field of a workflow template's cluster selector would be specified as placement.clusterSelector.zone.

  Also, field paths can reference fields using the following syntax:

  • Values in maps can be referenced by key:

    • labels['key']
    • placement.clusterSelector.clusterLabels['key']
    • placement.managedCluster.labels['key']
    • placement.clusterSelector.clusterLabels['key']
    • jobs['step-id'].labels['key']

  • Jobs in the jobs list can be referenced by step-id:

    • jobs['step-id'].hadoopJob.mainJarFileUri
    • jobs['step-id'].hiveJob.queryFileUri
    • jobs['step-id'].pySparkJob.mainPythonFileUri
    • jobs['step-id'].hadoopJob.jarFileUris[0]
    • jobs['step-id'].hadoopJob.archiveUris[0]
    • jobs['step-id'].hadoopJob.fileUris[0]
    • jobs['step-id'].pySparkJob.pythonFileUris[0]

  • Items in repeated fields can be referenced by a zero-based index:

    • jobs['step-id'].sparkJob.args[0]

  • Other examples:

    • jobs['step-id'].hadoopJob.properties['key']
    • jobs['step-id'].hadoopJob.args[0]
    • jobs['step-id'].hiveJob.scriptVariables['key']
    • jobs['step-id'].hadoopJob.mainJarFileUri
    • placement.clusterSelector.zone

  It may not be possible to parameterize maps and repeated fields in their entirety since only individual map values and individual items in repeated fields can be referenced. For example, the following field paths are invalid:

  • placement.clusterSelector.clusterLabels
  • jobs['step-id'].sparkJob.args
