Akira Ajisaka commented on HADOOP-15169:
----------------------------------------
In Apache Hadoop 3.x, the Jetty version is greater than 9.3.12 and it only
accepts TLS 1.2 by default. I don't want to add a setting to accept TLS 1.1 or
older protocols to create a security hole for now. When we have migrated to
Java 11 and Jetty 9.4.x to use TLS 1.3, then we can add the setting for Jetty
server.
On the other hand, in Apache Hadoop 2.x, adding the setting for HttpServer2
makes sense to me. That way we can avoid using SSLv2Hello, TLSv1, or TLSv1.1 in
HttpServer2.
> "hadoop.ssl.enabled.protocols" should be considered in httpserver2
