Subject [jira] [Commented] (HADOOP-12651) Replace dev-support with wrappers to Yetus
Date Wed, 20 Jan 2016 18:47:40 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12651?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15109117#comment-15109117
] 

Chris Douglas commented on HADOOP-12651:
----------------------------------------

In README.md:
* ASL header?
* s/wrappers scripts/wrapper scripts/
* Unescaped underscore in HADOOP_PATCHPROCESS
* Link to Yetus?

It'd be nice if the README or each wrapper included a brief description. Usage would come
from Yetus, but someone poking around might appreciate a one-liner that doesn't require them
to invoke anything to understand what's in dev-support.

Otherwise +1, pending jenkins. Speaking of jenkins, it won't be a problem for trunk/future
branches and branch-2 to invoke different dev-support scripts? I assume it's diverged already,
but thought I'd ask.

> Now that Yetus has had a release, we should rip out the components that make it up from
dev-support and replace them with wrappers.  The wrappers should:
> * default to a sane version
> * allow for version overrides via an env var
> * download into patchprocess
> * execute with the given parameters
> Marking this as an incompatible change, since we should also remove the filename extensions
and move these into a bin directory for better maintenance towards the future.
