Subject Re: no new topic created on Kafka
Date Tue, 28 Jul 2015 18:30:47 GMT
Hi, Yan:

      Thanks a lot for your reply.
     I tried to comment out systems.kafka.http-demo.samza.offset.default=oldest
and then I tried to comment out
systems.kafka.streams.http-demo.samza.offset.default=oldest
systems.kafka.streams.http-demo.samza.reset.offset=true

 The result is same as before.  1. the checkoutpoint topic was created, 2.
the log created by Logger can be found at /samza-container-0.log. 3. no
exception is at samza-container-0.log.

   I guess something conflict between HttpDemoParserStreamTask and
HttpDemoStatsStreamTask? Is any resource registered by
HttpDemoParserStreamTask and then HttpDemoStatsStreamTask can not recreate
a topic?

Sincerely,
Selina
