Summary: Update ciphers list for HttpFS
Key: HDFS-11816
URL: https://issues.apache.org/jira/browse/HDFS-11816
Project: Hadoop HDFS
Issue Type: Improvement
Components: httpfs, 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).
