Subject Re: New async producer NetworkClient endlessly trying to fetch metadata for deleted topics
Date Fri, 01 Apr 2016 16:04:19 GMT
Correction, it's much more often logging these warnings - every 100ms.
Current workaround is to regularly deploy fresh instance of app using
KafkaProducer, or recreate KafkaProducer instances, so that cache of
topics/partitions in it gets invalidated, cleared from deleted topics.
