      • getPermissionsListForShellHelp

        public static java.lang.String getPermissionsListForShellHelp()
        Helper method used by HBase shell to print all applicable permissions. Since HBase releases are not tied to a particular MapR release, this will ensure that any supported version of HBase shell will display correct help message applicable for the deployed version of MapR release.
        Returns:
        Help text to be displayed by HBase shell permission commands.
