You define variables by setting them with the Set Variable step in a transformation or by setting them in the kettle.properties file. The following variables are always defined: These variables are defined in a transformation: Internal.Transformation.Filename.Directory, Denormaliser - 2 series of key-value pairs.ktr, Denormaliser - 2 series of key-value pairs sample, Internal.Transformation.Repository.Directory. Now I am wondering are not we suppose to use these variables while using repository to define paths of sub-jobs or transformations? See the SS for the same. • Internal.Hadoop.TaskId is the taskID of the mapper, combiner, or reducer attempt context. Because the scope of an environment variable is too broad, Kettle variables were introduced to provide a way to define variables that are local to the job in which the variable is set. Whenever it is possible to use variables, it is also possible to use special characters (e.g. Pentaho Data Integration: The Parameter Object. parameters: stepmeta the stepmeta object to run.
