You can clone apache/samza locally and build it with: cd <samza-workspace> gradle -b bootstrap.gradle ./gradlew clean build -x test ./gradlew publishToMavenLocal ## This publishes a snapshot version of the latest apache/samza into your local maven repo Then, head to hello-samza workspace and build again: cd <hello-samza-workspace> mvn clean package ## This should create a build target ./bin/grid install zookeeper ./bin/grid start zookeeper ./bin/grid install kafka ./bin/grid start kafka ./bin/grid install yarn ./bin/grid start yarn mkdir -p deploy/samza tar -xvf ./target/hello-samza-*-SNAPSHOT-dist.tar.gz -C deploy/samza After this, you can follow steps in the tutorial to "Run" the example Samza job. HTH! Let me know if you need further help.

I tried again for the "latest" branch in hello-samza and it still works. > While installing it says "Building samza from master..." It is expected to build from "master" in apache/samza repo. So, the output line is expected. It is weird that you are unable to connect. Is it possible you are behind a firewall or something? Can you try to ping "git.apache.org" ? Or try the setup on a different box?

I tried on my host and it seems to be working. Can you give it another shot? If it still doesn't work, please let me know if you are running the command under the "master" or "latest" branch of samza-hello-samza. Thanks!
