### `dtutil`
Usage: `hadoop dtutil [-keytab` *keytab_file* `-principal` *principal_name* `]` *subcommand* `[-format (java|protobuf)] [-alias` *alias* `] [-renewer` *renewer* `]` *filename...*
Utility to fetch and manage hadoop delegation tokens inside credentials files. It is intended to replace the simpler command `fetchdt`. There are multiple subcommands, each with their own flags and options.
For every subcommand that writes out a file, the `-format` option will specify the internal format to use. `java` is the legacy format that matches `fetchdt`. The default is `protobuf`.
For every subcommand that connects to a service, convenience flags are provided to specify the kerberos principal name and keytab file to use for auth.
| SUBCOMMAND | Description |
|:---- |:---- |
| `print` <br/>&nbsp;&nbsp; `[-alias` *alias* `]` <br/>&nbsp;&nbsp; *filename* `[` *filename2* `...]` | Print out the fields in the tokens contained in *filename* (and *filename2* ...). <br/> If *alias* is specified, print only tokens matching *alias*. Otherwise, print all tokens. |
| `get` *URL* <br/>&nbsp;&nbsp; `[-service` *scheme* `]` <br/>&nbsp;&nbsp; `[-format (java|protobuf)]` <br/>&nbsp;&nbsp; `[-alias` *alias* `]` <br/>&nbsp;&nbsp; `[-renewer` *renewer* `]` <br/>&nbsp;&nbsp; *filename* | Fetch a token from service at *URL* and place it in *filename*. <br/> *URL* is required and must immediately follow `get`.<br/> *URL* is the service URL, e.g. *hdfs:&#47;&#47;localhost:9000*. <br/> *alias* will overwrite the service field in the token. <br/> It is intended for hosts that have external and internal names, e.g. *firewall.com:14000*. <br/> *filename* should come last and is the name of the token file. <br/> It will be created if it does not exist. Otherwise, token(s) are added to existing file. <br/> The `-service` flag should only be used with a URL which starts with `http` or `https`. <br/> The following are equivalent: *hdfs:&#47;&#47;localhost:9000/* vs. *http:&#47;&#47;localhost:9000* `-service` *hdfs* |
| `append` <br/>&nbsp;&nbsp; `[-format (java|protobuf)]` <br/>&nbsp;&nbsp; *filename* *filename2* `[` *filename3* `...]` | Append the contents of the first N filenames onto the last filename. <br/> When tokens with common service fields are present in multiple files, earlier files' tokens are overwritten. <br/> That is, tokens present in the last file are always preserved. |
| `remove -alias` *alias* <br/>&nbsp;&nbsp; `[-format (java|protobuf)]` <br/>&nbsp;&nbsp; *filename* `[` *filename2* `...]` | From each file specified, remove the tokens matching *alias* and write out each file using specified format. <br/> *alias* must be specified. |
| `cancel -alias` *alias* <br/>&nbsp;&nbsp; `[-format (java|protobuf)]` <br/>&nbsp;&nbsp; *filename* `[` *filename2* `...]` | Just like `remove`, except the tokens are also cancelled using the service specified in the token object. <br/> *alias* must be specified. |
| `renew -alias` *alias* <br/>&nbsp;&nbsp; `[-format (java|protobuf)]` <br/>&nbsp;&nbsp; *filename* `[` *filename2* `...]` | For each file specified, renew the tokens matching *alias* and write out each file using specified format. <br/> *alias* must be specified. |
### `fs` ### `fs`
This command is documented in the [File System Shell Guide](./FileSystemShell.html). It is a synonym for `hdfs dfs` when HDFS is in use. This command is documented in the [File System Shell Guide](./FileSystemShell.html). It is a synonym for `hdfs dfs` when HDFS is in use.
