Well, I think that would be a nice feature to have:
hadoop namenode -reformat -y
What do you think?
Can you add it to the HDFS´s Jira?

Hi,

When I try to reformat HDFS (I have to multiple times for some experiment I need to run), it asks for a confirmation Y/N. Is there a way to disable this in HDFS/hadoop? I am trying to automate my process and pressing Y everytime I do this is just a lot of manual work.

Thanks,
Virajith
