Hi Peruvian,

 

Did you get a chance to refer document[1] which may help you to recover NameNode.

Hi @senthh 

 

Thanks for the information, but unfortunately they made a format to the namenode and they don't have a backup. Now I'm looking for how to recover the information from the datanode you know somehow.

Greetings.
