John Zhuge commented on HADOOP-14417: ------------------------------------- [~andrew.wang] or [~steve_l], could you please comment? The default cipher list was added in HADOOP-14083. This patch removes 5 DHE ciphers from the default list. I have verified the removal does not break HADOOP-14083. > 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 > Attachments: HADOOP-14417.branch-2.001.patch > > > 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.
