Syntax

You can change the modes of directories and files in the Data Fabric storage using either the hadoop fs command with the -chmod option, or using the chmod command via NFS. The syntax for both commands is similar:

  • hadoop fs -chmod [-R] <MODE>[,<MODE>]... | <OCTALMODE> <URI> [<URI> ...]
  • chmod [-R] <MODE>[,<MODE>]... | <OCTALMODE> <URI> [<URI> ...]

Parameters and Options

The following table provides the command parameters and options with their descriptions:
