> 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).
