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

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?
Regards

Simply do a "yes Y | hadoop namenode -format".

You could pipe 'yes' to the hadoop command:

yes | hadoop namenode -format

Cool...yeah "echo Y | hadoop namenode -format" works just fine.
