Subject [jira] [Commented] (HADOOP-14816) Update Dockerfile to use Xenial
Date Thu, 19 Oct 2017 00:43:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-14816?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16210391#comment-16210391

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/].

life support from Ubuntu.
