Re: Error upgrading KafkaStreams

[Bruno Cadonna]

Hi Murilo,

Did you retry to upgrade again after you reset the application? Did it work?

Best,
Bruno

Hi Bruno
Thanks for your response.
No, I did not reset the application prior to upgrading. That was simply
upgrading KafkaStreams from 2.4 to 2.7.

I was able to reproduce it on a smaller environment, and it does indeed
recover.
In a large environment, though, it keeps like that for hours. In this same
large environment, I had to downgrade the application, and when doing that
I did reset the application, which just took a few minutes.

Thanks
Murilo

Hi Murilo,

No, you do not need any special procedure to upgrade from 2.4 to 2.7.

What you see in the logs is not an error but a warning. It should not
block you on startup forever. The warning says that the local states of
task 7_17 are corrupted because the offset you want to fetch of the
state changelog topic partition
my-assembler-4-KTABLE-AGGREGATE-aggregated-topic-changelog-17 is larger
or smaller than the offsets that exist on the brokers for that
partition. If Streams runs into such an exception it will recreate the
state from scratch which might take a while depending on the size of the
state.

The root cause of this warning is not clear from the information you
gave. Did you maybe reset the application but not wipe out the local
state stores?

Best,
Bruno

Hi
I have Kafka brokers running on version 2.4.1, with a KafkaStreams app on
2.4.0.
I'm trying to upgrade my KafkaStreams to v2.7.0, but I got my instances
stuck on startup.
In my understanding, I don't need any special procedure to upgraded from
KStreams 2.4.0 to 2.7.0, right?

The following error stands out for me:
