If you stopped the cluster immediately you may have a chance to restore most of
the data.
It's a manual and hacky process.
You can use the Offline Edits Viewer to see the latest edits and cut off the
d
h the modifies edits log.
Hope this helps.
Thanks,

If the directory has snapshot enabled, the file can be retrieved from the
past snapshots.
Otherwise, the file inodes are removed from namenode metadata, and blocks
are scheduled for deletion.
You might want to play with edit log
y and does not guarantee the blocks are still there.

Hi
Basically it deletes metadata. If you have backup from metadata you
maybe can restore.

some one mistakenly do a rm -skipTrash operation on the HDFS, but we stop
the namenode and datanodes immediately. (CDH 5.4.5)
