### `classpath`
Usage: `yarn classpath`
Usage: `yarn classpath [--glob |--jar <path> |-h |--help]`
Prints the class path needed to get the Hadoop jar and the required libraries
| COMMAND\_OPTION | Description |
|:---- |:---- |
| `--glob` | expand wildcards |
| `--jar` *path* | write classpath as manifest in jar named *path* |
| `-h`, `--help` | print help |
