> Project: Hadoop Core
> Issue Type: Bug
> Components: contrib/hdfsproxy
> Affects Versions: 0.21.0
> Reporter: zhiyong zhang
> Assignee: zhiyong zhang
> Fix For: 0.21.0

>
> 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.
