Emanuele Cesena commented on KAFKA-4350:
----------------------------------------
[~hachikuji] Sorry, I'm a bit confused. I need to replicate from Kafka 0.9 to
0.10.
I don't think MM 0.9 works for writing to Kafka 0.10, or at least I've tried it
in my settings (i.e., K 0.9 -> MM 0.9 -> K 0.10), it didn't work, then I read
around and always saw recommendations to use the new MM against the old broker,
not viceversa.
So I went for MM 0.10: K 0.9 -> MM 0.10 -> K 0.10.
In this case, I can use either the new client or the old client (setting
bootstrap.servers vs zookeeper.connect).
I understand that the new client may not work for reading from K 0.9.
But supposedly, the old client (in MM 0.10) should work, shouldn't it? This is
the core of the issue I'm reporting, I'm getting errors even with the old
client.
