Currently, logs involving PartitionState are not very helpful. ``` Broker 449 cached leader info org.apache.kafka.common.requests.UpdateMetadataRequest$PartitionState3285d64a for partition <topic>-<partition> in response to UpdateMetadata request sent by controller 356 epoch 138 with correlation id 0 TRACE state.change.logger: Broker 449 received LeaderAndIsr request org.apache.kafka.common.requests.LeaderAndIsrRequest$PartitionState66d6a8eb correlation id 3 from controller 356 epoch 138 for partition [<topic>,<partition>] ``` Author: Ashish Singh <asingh@cloudera.com> Reviewers: Ismael Juma <ismael@juma.me.uk> Closes #1609 from SinghAsDev/partitionStatepull/1647/head
