["Lei (Eddy) Xu (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HDFS-6673?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Lei (Eddy) Xu updated HDFS-6673:
--------------------------------
    Attachment: HDFS-6673.004.patch

This patch firstly pre-scans the fsimage to load directories and uses directory metadata to build namespace in LevelDB. 
The second scan directly outputs inode as Delimited output as the order the inode presented in the fsimage.

Referred INode is not currently supported, so that each inode only generates one text entry.
