The Node Labels File

The node labels file defines labels for cluster nodes, to identify them for the purpose of specifying where to run jobs. Each line in the node label file consists of an identifier that specifies one or more nodes, along with one or more labels to apply to the specified nodes, separated by whitespace.

<identifier> <labels>

Warning:

Tabs cannot be used for whitespace. If tabs are used, the node label list will be empty.

  • The labels are a comma-delimited list of labels to apply to the nodes matched by the identifier. Labels that contain whitespace should be enclosed in single or double quotation marks.
