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.
