Description

We've seen defective applications cause havoc on the NameNode, for e.g. by doing 100k+ 'listStatus' on very large directories (60k files) etc.

I'd like to start a discussion around how we prevent such, and possibly malicious applications in the future, taking down the NameNode.

Thoughts?
