> There exists a race condition in the Trogdor produce bench worker code where `WorkerUtils#createTopics()` [notices the topic exists|https://github.com/apache/kafka/blob/4824dc994d7fc56b7540b643a78aadb4bdd0f14d/tools/src/main/java/org/apache/kafka/trogdor/common/WorkerUtils.java#L159] yet when it goes on to verify the topics, the DescribeTopics call throws an `UnknownTopicOrPartitionException`.
> We should add sufficient retries such that this does not fail the task.
