      KMS_HTTP_PORT | hadoop.kms.http.port | kms-site.xml
      KMS_MAX_HTTP_HEADER_SIZE | hadoop.http.max.request.header.size and hadoop.http.max.response.header.size | kms-site.xml

    Description

      The Tomcat 6 we are using will reach EOL at the end of 2017. While there are other good options, I would propose switching to Jetty 9 for the following reasons:

      • Easier migration. Both Tomcat and Jetty are based on Servlet Containers, so we don't have change client code that much. It would require more work to switch to JAX-RS.
      • Well established.
      • Good performance and scalability.

      Other alternatives:

      • Jersey + Grizzly
      • Tomcat 8

      Your opinions will be greatly appreciated.
