Vijay Singh commented on HADOOP-12668:
--------------------------------------
Hi [~wheat9],
Based on current jetty depndency in pom (release 6), setInluceCiphersuites is
not available for SSLSocketConnector yet. Please refer the maven for current
jetty dependency.
http://mvnrepository.com/artifact/org.mortbay.jetty/jetty/6.1.26
I suggest that we open a new ticket to include cipher suites when we upgrade
jetty version in pom. I am going to open two jira issues: 1) To upgrade jetty
and 2) To include cipher suites based on configuration.
> Modify HDFS embeded jetty server logic in HttpServer2.java to exclude weak
> Ciphers through ssl-server.conf

> Key: HADOOP-12668
> URL: https://issues.apache.org/jira/browse/HADOOP-12668
> Project: Hadoop Common
> Issue Type: Improvement
> Components: security
> Affects Versions: 2.7.1
> Reporter: Vijay Singh
> Assignee: Vijay Singh
> Priority: Critical
> Labels: common, ha, hadoop, hdfs, security
> Attachments: Hadoop-12668.006.patch

> Original Estimate: 24h
> Remaining Estimate: 24h
>
> Currently Embeded jetty Server used across all hadoop services is configured
> through ssl-server.xml file from their respective configuration section.
> However, the SSL/TLS protocol being used for this jetty servers can be
> downgraded to weak cipher suites. This code changes aims to add following
> functionality:
> 1) Add logic in hadoop common (HttpServer2.java and associated interfaces) to
> spawn jetty servers with ability to exclude weak cipher suites. I propose we
> make this though ssl-server.xml and hence each service can choose to disable
> specific ciphers.
> 2) Modify DFSUtil.java used by HDFS code to supply new parameter
> ssl.server.exclude.cipher.list for hadoop-common code, so it can exclude the
> ciphers supplied through this key.
