Description

Currently hdfsproxy unit test uses Cactus in-container test. It uses three fixed ports. one for tomcat start-up/shut-down, another for tomcat http-port and the third for tomcat https-port.
If theses ports are already in use, ant build will fail. To fix this, we decided to use a java program to probe the free ports dynamically and update the tomcat conf with these free ports.
