Chris Douglas commented on HADOOP-14816:
----------------------------------------
bq. I'm viewing as incompatible in that it will likely change the requirements
for any binary distributions and, if I read the new hadoop compatibility
guidelines that were just committed, the minimum versions of the compilers
After HADOOP-14897, I don't think this is an incompatible change as defined by
the compatibility guidelines. If it is, then we should update them again.
bq. I don't want to preclude anyone from building their own Trusty binaries
either
Agreed, but limiting our test infrastructure to Trusty is both painful and not
sufficient to guarantee that property. We can keep and maintain Dockerfiles for
testing with other/older distributions, but running the default build/test
environment in Trusty requires workarounds that cost dev cycles and test time.
Support for Trusty is uncontroversial, I think we're all on the same page,
there.
I'm +1 on the patch. Other than dismay that we still use forrest, it updates
the existing Dockerfile to follow [best
practices|https://docs.docker.com/engine/userguide/eng-image/dockerfile_best-practices/].
