Subject [jira] [Commented] (HADOOP-12668) Modify HDFS embeded jetty server logic in HttpServer2.java to exclude weak Ciphers through ssl-server.conf
Date Thu, 14 Jan 2016 10:42:39 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12668?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15097974#comment-15097974

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. 

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.

> 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.
