Paolo Patierno updated KAFKA-5469:
----------------------------------
Description:
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 ..
