> {{ZkController::getLeader}} does not handle InterruptedException, and instead rethrows it as a SolrException. There's a couple other improvements we could make around the exception handling as well:
> * Not using exceptions for flow control
> * Avoid log-and-rethrow
> * The exception message could provide remedy steps
