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)
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][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
Optional. Validation rules to be applied to this parameter’s value.
