[PR] KAFKA-20746 NPE in MetadataCache#toCluster (#22723) [kafka]

["brandboat (via GitHub)" <gi...@apache.org>]

brandboat opened a new pull request, #22800:
URL: https://github.com/apache/kafka/pull/22800

   MetadataCache#toCluster builds a Cluster view for quota callbacks. Previously,  it filtered fenced brokers out of the broker-to-node map, but partition metadata  can still reference fenced brokers as replicas. When such replicas were converted  to PartitionInfo, the missing broker entry could cause a NullPointerException.
   
   Include all registered brokers in the broker-to-node map so fenced replicas can  be represented as offline replicas in the generated Cluster.
