Subject [jira] [Commented] (HDFS-9241) HDFS clients can't construct HdfsConfiguration instances
Date Tue, 20 Oct 2015 19:20:27 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9241?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14965593#comment-14965593

Steve Loughran commented on HDFS-9241:
--------------------------------------

Netty? client side? I thought changes in ZK's dependencies there was what was breaking hadoop-hdfs
builds on bigtop (HADOOP-12415). hdfs-client shouldn't be needing netty. There's no jersey,
none of its bits, and you could probably cull curator.

> the changes for the hdfs client classpath make instantiating {{HdfsConfiguration}} from
the client impossible; it only lives server side. This breaks any app which creates one.
> I know people will look at the {{@Private}} tag and say "don't do that then", but it's
worth considering precisely why I, at least, do this: it's the only way to guarantee that
the hdfs-default and hdfs-site resources get on the classpath, including all the security
settings. It's precisely the use case which {{HdfsConfigurationLoader.init();}} offers internally
to the hdfs code.
> What am I meant to do now?
