Files and Folders¶

At the moment the following filesystems are supported:

Local Fileystem¶

File¶

Creates a file-upload field where one file can be selected and uploaded.

- id: image
  description: Image
  type: local_file

uploaded file will be copied into local workspace
contains absolute path to the uploaded file
all input files will be deleted after job run

Folder¶

Creates a file-upload field where multiple files can be selected and uploaded.

- id: image
  description: Images
  type: local_folder

uploaded files will be copied into local workspace
contains absolute path to the folder which contains all uploaded files
all input files will be deleted after job run

HDFS (Apache Hadoop)¶

File¶

Creates a file-upload field where file can be selected and uploaded.

- id: image
  description: Images
  type: hdfs_file

uploaded file will be imported into HDFS
contains path to the imported file into the HDFS filesystem
all input files will be deleted after job run

Folder¶

Creates a file-upload field where one or multiple files can be selected and uploaded.

- id: image
  description: Images
  type: hdfs_folder

uploaded files will be imported into HDFS
contains path to the HDFS folder where all imported files were stored
all input files will be deleted after job run

Filetypes¶

The accept attribute specifies the types of files that the server accepts. Per default all files can be selected and uploaded.

- id: image
  description: Image
  type: local_file
  accept: .jpg

To specify more than one file, separate the values with a comma (e.g. accept: .jpg, .gif). Most of the browsers are not able to handle two dots in the extension (e.g. .tar.gz). Please use .gz.
