HDFS File Permission (legacy)

This is a legacy file handling node and will be replaced in the foreseeable future. For further information about the new file handling framework see the File Handling Guide.

This node allows to change the file permissions of HDFS files and directories. Permissions are managed in three distinct scopes e.g. user, group, and others. Character 2, 3 and 4 specify the user rights, 5, 6 and 7 the group rights and 8,9 and 10 the rights for all other users. Character 1 specifies if the file is a file "-" or directory "d" and can not changed. The following table illustrates some of the possible permissions:
