Review comment:
Thank @saintstack for reviewing.
For JMXConnectorServer starting, only use the default port or specifying
port, can't find a free port by retrying. So I use
HBaseTestingUtility#randomFreePort to get a free port, which mark ports as
taken and don't return repeated ports. This patch may not completely avoid port
clash, but at least it can reduce the possibility ?
