------------------------------------
Summary: 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
Fix For: 2.7.2
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.
