Description

HADOOP-14003 enabled the customization of Tomcat attribute protocol, acceptCount, and acceptorThreadCount for KMS in branch-2. See https://tomcat.apache.org/tomcat-6.0-doc/config/http.html.

KMS switched from Tomcat to Jetty in trunk. Only acceptCount has a counterpart in Jetty, acceptQueueSize. See http://www.eclipse.org/jetty/documentation/9.3.x/configuring-connectors.html.
