> In the StreamPartitionAssignor class, the created state changelog topics aren't not logged
correctly if the DEBUG log level is set.
> {code}
> [2017-06-19 12:18:44,186] DEBUG stream-thread [streams-temperature-6d25c7ff-0927-4469-8ab3-24444685e7d8-StreamThread-1]
Created state changelog topics {streams-temperature-KSTREAM-REDUCE-STATE-STORE-0000000002-changelog=org.apache.kafka.streams.processor.internals.StreamPartitionAssignor$InternalTopicMetadata@65ae7693}
from the parsed topology. (org.apache.kafka.streams.processor.internals.StreamPartitionAssignor:477)
> {code}
> against repartition topics which are well logged :
> {code}
> [2017-06-19 12:18:37,871] DEBUG stream-thread [streams-temperature-6d25c7ff-0927-4469-8ab3-24444685e7d8-StreamThread-1]
Created repartition topics [Partition(topic = streams-temperature-KSTREAM-REDUCE-STATE-STORE-0000000002-repartition,
partition = 0, leader = none, replicas = [], isr = [])] from the parsed topology. (org.apache.kafka.streams.processor.internals.StreamPartitionAssignor:402)
> {code}
> At same time if source topics are not created before launching the stream application,
the state changelog topics log shows just {} (the placeholder) while for repartition topics
the [] that is right because it's an empty list.
> It seems that there are two problems. For state changelog topics the values() is not
used but then InternalTopicMetadata hasn't a toString() for having a well formatted output.
> I'm already working on that ..
