Oops...

I executed the following command:

./hadoop dfs -rmr .

Everything on the DFS, including the trash seems to be deleted. Is there a way to recover my data?

Depending which version of Hadoop you are running ... In 0.12.x it would be enough to kill -9 the NameNode ASAP, and remove this deletion operation from the editlog, before it gets re-integrated with fsimage.

DO MAKE A BACKUP OF THESE FILES FIRST !!!
