Hey Liaowenrui,
See the [comment|https://issues.apache.org/jira/browse/HADOOP-8721?focusedCommentId=13405151&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13405151] for details on your question. It can clear some of your basic doubt and can check more on NFS tutorials for further.
Please post such questions in mailing lists rather than in JIRAs.
JIRA is mainly for tracking the confirmed bugs.
