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 delete transactions
that was issues by mistake.
Then you can restart the namenode with the modifies edits log.
Hope this helps.
