Subject [jira] [Commented] (HADOOP-14417) Update cipher list for KMS
Date Fri, 12 May 2017 17:34:04 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-14417?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16008438#comment-16008438

Lei (Eddy) Xu commented on HADOOP-14417:

Thanks for picking this, [~jzhuge]. 

Please rename the patch against {{branch-2}}. I give +1 pending a new jenkins run.

It'd nice to have more inputs on the compatibility concerns in branch-2, [~andrew.wang], [~steve_l].

> 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).
