示例1: getDefaultFileContext
import org.apache.hadoop.conf.Configuration; //導入方法依賴的package包/類
/**
* Get default file system URI for the cluster (used to ensure consistency
* of history done/staging locations) over different context
*
* @return Default file context
*/
private static FileContext getDefaultFileContext() {
// If FS_DEFAULT_NAME_KEY was set solely by core-default.xml then we ignore
// ignore it. This prevents defaulting history paths to file system specified
// by core-default.xml which would not make sense in any case. For a test
// case to exploit this functionality it should create core-site.xml
