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?
