[jira] Created: (HDFS-945) Make NameNode resilient to DoS attacks (malicious or otherwise)

Make NameNode resilient to DoS attacks (malicious or otherwise)
---------------------------------------------------------------

                 Key: HDFS-945
                 URL: https://issues.apache.org/jira/browse/HDFS-945
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: name-node
            Reporter: Arun C Murthy


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?
