+Prints the class path needed to get the Hadoop jar and the required libraries. If called
without arguments, then prints the classpath set up by the command scripts, which is likely
to contain wildcards in the classpath entries. Additional options print the classpath after
wildcard expansion or write the classpath into the manifest of a jar file. The latter is useful
in environments where wildcards cannot be used and the expanded classpath exceeds the maximum
supported command line length.
