Hello Samza, Many Samza tutorials (including the official one) still use old apache git link to clone repository (e.g., git clone https://git.apache.org/samza-hello-samza.git hello-samza). However, this link is no longer valid. It might be better to update the old link to https://github.com/apache/samza-hello-samza.git in the official tutorial. Thanks!
Best, Yang
