John Zhuge created HADOOP-14417:
-----------------------------------

             Summary: Update cipher list for KMS
                 Key: HADOOP-14417
                 URL: https://issues.apache.org/jira/browse/HADOOP-14417
             Project: Hadoop Common
          Issue Type: Improvement
          Components: kms, security
    Affects Versions: 2.9.0
            Reporter: John Zhuge
            Assignee: John Zhuge
            Priority: Minor


In Oracle Linux 6.8 configurations, the curl command cannot connect to certain CDH services that run on Apache Tomcat when the cluster has been configured for TLS/SSL. Specifically, HttpFS, KMS, Oozie, and Solr services reject connection attempts because the default cipher configuration uses weak temporary server keys (based on Diffie-Hellman key exchange protocol).
