Subject [jira] [Commented] (HADOOP-14672) Shaded Hadoop-client-minicluster include unshaded classes, like: javax, sax, dom, etc.
Date Wed, 19 Jul 2017 22:08:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-14672?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16093874#comment-16093874

Sean Busbey commented on HADOOP-14672:

let's just fold this under HADOOP-14089. They have the same basic prerequisite: we need to
automate checking for non-relocated classes in all of the shaded artifacts.

{quote} I also see some mapreduce, hdfs, common classes are unshaded. At the same time, some
other classes are shaded. I assume we should make them all shaded.

The terminology around making bundled artifacts is often confusing. Here, do you mean "included
in a jar that is built from the contents of other jars" or do you mean "relocated to be in
a java package under org.apache.hadoop"?

The various client jars should contain contents from other jars, but just those needed for
the given jar's particular purpose. In the case of the hadoop-client-minicluster artifact
that should be the classes needed to run an instance of the various miniclusters for testing
purposes, but none of the things included in hadoop-client-api or hadoop-client-runtime. Any
classes included ought to be in a package under org.apache.hadoop (I think the default is
to put them in {{org.apache.hadoop.shaded._original_package_}}.

we can see: javax, dom, sax, etc. are all unshaded.
