That's part of the new consumer API that hasn't been released yet. The API happens to be included in the 0.8.2.* artifacts because it is under development, but isn't yet released -- it hasn't been mentioned in the release notes, nor is it in the official documentation: http://kafka.apache.org/documentation.html
That API is currently under active development and should be available in the next release. If you want to test it out, you can use build a copy yourself of trunk, but the high-level consumer functionality is not yet implemented so it likely does not include everything you want. For the time being, you probably want to use the existing high level consumer API: http://kafka.apache.org/documentation.html#highlevelconsumerapi On Wed, Apr 29, 2015 at 11:07 PM, Gomathivinayagam Muthuvinayagam < sankarm...@gmail.com> wrote: > Thank you, > > It seems the following methods are not supported in KafkaConsumer.
