Allen Wittenauer resolved HDFS-945.
-----------------------------------

    Resolution: Duplicate

I'm going to dupe this to HADOOP-9194.

> 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: namenode
>            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?
