Mike Drob commented on SOLR-9155:
---------------------------------
Can somebody take a look at this? I saw this happen on a live system and think
it would be good to improve the logging around it for my ops team.
> Improve ZkController::getLeader exception handling

> {{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
