示例1: testChgrpGroupValidity

import org.apache.hadoop.fs.shell.FsCommand; //导入依赖的package包/类
/**
 * Tests valid and invalid group arguments to chgrp.
 */
@Test
public void testChgrpGroupValidity() {
  // This test only covers argument parsing, so override to skip processing.
  FsCommand chgrp = new FsShellPermissions.Chgrp() {
    @Override
    protected void processArgument(PathData item) {
    }
  };
  chgrp.setConf(new Configuration());

  // The following are valid (no exception expected).
  chgrp.run("group", "/path");

  // The following are valid only on Windows.
  assertValidArgumentsOnWindows(chgrp, "Group With Spaces", "/path");

  // The following are invalid (exception expected).
  assertIllegalArguments(chgrp, ":gr#oup", "/path");
  assertIllegalArguments(chgrp, ":gr%oup", "/path");
}

示例2: registerCommands

import org.apache.hadoop.fs.shell.FsCommand; //导入依赖的package包/类
protected void registerCommands(CommandFactory factory) {
  // TODO: DFSAdmin subclasses FsShell so need to protect the command
  // registration.  This class should morph into a base class for
  // commands, and then this method can be abstract
  if (this.getClass().equals(FsShell.class)) {
    factory.registerCommands(FsCommand.class);
  }
}
