-- Distributes the entries (images) in a training dataset across the
-- training dataset and the test dataset for a project.
-- @DistributeDatasetEntries@ moves 20% of the training dataset images to
-- the test dataset. An entry is a JSON Line that describes an image.
--
-- You supply the Amazon Resource Names (ARN) of a project\'s training
-- dataset and test dataset. The training dataset must contain the images
-- that you want to split. The test dataset must be empty. The datasets
-- must belong to the same project. To create training and test datasets
-- for a project, call CreateDataset.
--
-- Distributing a dataset takes a while to complete. To check the status
-- call @DescribeDataset@. The operation is complete when the @Status@
-- field for the training dataset and the test dataset is
-- @UPDATE_COMPLETE@. If the dataset split fails, the value of @Status@ is
-- @UPDATE_FAILED@.
--
-- This operation requires permissions to perform the
-- @rekognition:DistributeDatasetEntries@ action.
