Miklos Szegedi commented on HADOOP-14897:
-----------------------------------------
[~chris.douglas]. Given we are talking about external dependencies, we cannot
assume that they use the same versioning standard. However, talking about
Hadoop versioning standard, I would assume that a minor release requires only
minor releases in dependencies. Let's be more specific with an example. If we
ship Hadoop 5.0 with support for C++ standards before C++14, this requirement
would assume that 5.1 will not add a requirement of C++14 as a minimum.
In case of Java I would rephrase this question, would you allow Hadoop 2.9 ship
with a requirement of Java 8, if 2.8 depended on Java 7 before?
