Subject Re: Kafka 0.9 producer doesn't work
Date Thu, 21 Jan 2016 02:29:11 GMT
Hello.

I packaged it to an executable jar file and executed it on the VM, and yes,
it was successfully worked.

I'm really confuse why it didn't work on my Windows10 environment where is
on the host environment and worked well on the VM environment... It is
weird indeed.

Best regards

Kim
