Subject Re: NoSuchMethodError in KafkaReciever
Date Fri, 07 Mar 2014 00:32:22 GMT
I dont have a Eclipse setup so I am not sure what is going on here. I would
try to use maven in the command line with a pom to see if this compiles.
Also, try to cleanup your system maven cache. Who knows if it had pulled in
a wrong version of kafka 0.8 and using it all the time. Blowing away the
cache and clean compiling will make sure the right kafka will be loaded.

Hope this helps.
