Subject [jira] [Commented] (HADOOP-14897) Loosen compatibility guidelines for native dependencies
Date Fri, 22 Sep 2017 17:41:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-14897?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16176793#comment-16176793

Chris Douglas commented on HADOOP-14897:

bq. I would assume that a minor release requires only minor releases in dependencies
That's a reasonable proposal. As I read the current draft, upgrading minor versions of dependencies
is prohibited.

bq. C++ standards before C+14, this requirement would assume that 5.1 will not add a requirement
of C+14 as a minimum
Also reasonable, but also different from the current text.

bq. would you allow Hadoop 2.9 ship with a requirement of Java 8, if 2.8 depended on Java
7 before?
To use this example, I would not require that Hadoop compile and run against a particular
build of openjdk. That's too restrictive.
