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> ...]
