     [ https://issues.apache.org/jira/browse/HDFS-7043?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Eason updated HDFS-7043:
------------------------
    Environment: linux  (was: I have delete all the data dir on the namenode,causing lost
of all the data.
I can only recover a edit.new file from the disk, whtich is quite huge(12GB),
Maybe most of recent operation is on the edit log
Is it possible to recover data from this edit log file?

Try to add all the file or direcotry on every edit log to recover the filesystem?

anyone could help?
many thx)
