Re: LeaderNotAvailable Exception
Hi Neha,

Previously I have tried with trunk branch. After I have tried with 0.7
stable version. Now I am able to run some samples.

Thanks for your immediate responses.

I have only one small doubt. Can we set requests to be consumed by only one
consumer, means like a pull operation. Once consumed it shouldn't be
available for other consumers. Is this possible?

I am very new to kafka, that's why I am asking this.

Thanks in advance.

Thanks,
PrasannaKumar.

That seems like a bug. Would you mind filing a JIRA and explaining your
test there so we can reproduce and fix the issue ?

Thanks,
Neha
