Class Classpath

org.apache.hadoop.util.Classpath

@Private
public final class Classpath
extends Object

Command-line utility for getting the full classpath needed to launch a Hadoop client application. If the hadoop script is called with "classpath" as the command, then it simply prints the classpath and exits immediately without launching a JVM. The output likely will include wildcards in the classpath. If there are arguments passed to the classpath command, then this class gets called. With the --glob argument, it prints the full classpath with wildcards expanded. This is useful in situations where wildcard syntax isn't usable. With the --jar argument, it writes the classpath as a manifest in a jar file. This is useful in environments with short limitations on the maximum command line length, where it may not be possible to specify the full classpath in a command. For example, the maximum command line length on Windows is 8191 characters.
