>             Project: Accumulo
>          Issue Type: Bug
>          Components: master, tserver
>    Affects Versions: 1.5.0, 1.5.1, 1.5.2, 1.6.0, 1.6.1
>            Reporter: Josh Elser
>             Fix For: 1.5.3, 1.7.0, 1.6.3
> When a thrift server is configured to use a fixed port, we will loop 100 times trying
to bind to the port which is (likely) going to stay bound. Because the server socket is setting
SO_REUSEADDR, we shouldn't have issues where the previous application has died/gone-away,
but being unable to bind to it.
> If we're explicitly given a port to start the thrift server on, and are unable to start
it, I think it would be better to throw an exception which would kill the process instead
of retrying at least 25 seconds first.
> Because we've already copied TNonblockingServerSocket, we can modify the TTransportException
thrown with a more meaningful exception and work on getting better semantics in upstream thrift
(if necessary).
