Cloudera will mantain community support and fixes for the versions above?
I thought that the term open source referred to having access to the source code. When you say that to download the software/code for newer version you need a username and password provided by a subscription, I understand that new version are no longer open-source. I am wrong?
As I mentioned in my preceding answer you will need to have a subscription agreement with Cloudera, moving forward, to gain access to updates. Yes, Cloudera is open source in the sense that all of our individual projects and code are pushed upstream to the individual open source projects. However, to gain access to the software from Cloudera i.e. our distribution you will need a subscription agreement.
