Subject Re: Same error when using an ubuntu (15.10) image
Date Fri, 15 Jan 2016 18:43:48 GMT
Hey Yi,

sorry for the confusion, my Java experience is... limit... :)
OK, I have to check out samza first, in hindsight that sounds not too
unreasonable.
But if I read './gradlew' I assume within the samza-checkout there should
be a gradlew file.
###
root@0437b8c9238a:/opt/apache-samza-0.10.0-src# find . -name gradlew
root@0437b8c9238a:/opt/apache-samza-0.10.0-src#
###

Du I have to reference the gradlew file from the hello-samza repository?

Thanks for walking in my shoes a bit. Let's say afterwards you would have a
howto that serve java-rockies like me as well. :)

Cheers
Christian
