示例1: writePasswordFile
import com.cloudera.sqoop.config.ConfigurationConstants; //导入依赖的package包/类
/**
* Writes the user's password to a tmp file with 0600 permissions.
* @return the filename used.
*/
public static String writePasswordFile(Configuration conf)
throws IOException {
// Create the temp file to hold the user's password.
String tmpDir = conf.get(
ConfigurationConstants.PROP_JOB_LOCAL_DIRECTORY, "/tmp/");
File tempFile = File.createTempFile("mysql-cnf", ".cnf", new File(tmpDir));
// Make the password file only private readable.
DirectImportUtils.setFilePermissions(tempFile, "0600");
// If we're here, the password file is believed to be ours alone. The
// inability to set chmod 0600 inside Java is troublesome. We have to
// trust that the external 'chmod' program in the path does the right
// thing, and returns the correct exit status. But given our inability to
// re-read the permissions associated with a file, we'll have to make do
// with this.
String password = DBConfiguration.getPassword((JobConf) conf);
BufferedWriter w = new BufferedWriter(new OutputStreamWriter(
new FileOutputStream(tempFile)));
w.write("[client]\n");

w.close();
return tempFile.toString();

* perform work.
* @return a File describing a directory where local temp data for the
* task attempt can be stored.
