Subject [jira] [Commented] (HADOOP-14387) new Configuration().get() fails if core-site.xml isn't on the classpath
Date Mon, 08 May 2017 19:08:04 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-14387?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16001351#comment-16001351

Jonathan Eagles commented on HADOOP-14387:
------------------------------------------

[~stevel@apache.org], still eager to get to the bottom of this but I still need help trying
to reproduce the failure as stated in the summary. Can you please provide a stack trace or
reproducible case that can cause this to fail. I have tried to reproduce this case with the
test code above. As you can see from my results, a core-site.xml missing from the classpath
is treated as optional based on these steps.

>         Environment: test run in downstream project with no core-site in test/resources

> If you try to create a config via {{new Configuration()}} and there isn't a {{core-site.xml}}
on the CP, you get a stack trace. Previously it'd just skip the failure to load.
> This is a regression which breaks downstream apps that don't need a core-site to run,
but do want to load core-default &c
