> When running a secure data node, the default ports it uses are 1004 and 1006. Sometimes other OS services can start on these ports causing the DN to fail to start (eg the nfs service can use random ports under 1024).
> When this happens an error is logged by jsvc, but it is confusing as it does not tell you which port it is having issues binding to, for example, when port 1004 is used by another process:

> We should catch the BindException exception and log out the problem address:port and then re-throw the exception to make the problem more clear.
> I will upload a patch for this.
