> ConsumeKafka(Record)_2_0, ConsumeKafka(Record)_2_6 do not reconnect if using
> statically assigned partitions

> Key: NIFI-8357
> URL: https://issues.apache.org/jira/browse/NIFI-8357
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Reporter: Mark Payne
> Assignee: Mark Payne
> Priority: Critical
> Fix For: 1.14.0
>
> Time Spent: 20m
> Remaining Estimate: 0h
>
> If using statically assigned partitions in ConsumeKafka_2_0,
> ConsumeKafkaRecord_2_0, ConsumeKafka_2_6, or ConsumeKafkaRecord_2_6 (via
> adding {{partitions.}}{{<hostname}}> properties), when a client connection
> fails, it recreates connections but does not properly assign the partitions.
> As a result, the consumer stops consuming data from its partition(s), and the
> Kafka client that gets created gets leaked. This can slowly build up to
> leaking many of these connections and potentially could exhaust heap or cause
> IOException: too many open files.
