Bessenyei Balázs Donát commented on FLUME-3020:
-----------------------------------------------
Under what circumstances does {{InetAddress.getLocalHost()}} throw
{{UnknownHostException}}?
If the chances are not negligible, maybe we should just go "lazy" and cache it
when it's first required (possibly as String).
> Improve HDFSEventSink Escape Ingestion by more then 10x by not getting
> InetAddress on every record
