> distcpv2 and distcpv1 jars should not coexist
> ---------------------------------------------
>
> Key: HADOOP-8327
> URL: https://issues.apache.org/jira/browse/HADOOP-8327
> Project: Hadoop Common
> Issue Type: Bug
> Affects Versions: 0.23.2
> Reporter: Dave Thompson
> Assignee: Dave Thompson
> Attachments: HADOOP-8327-branch-0.23.2.patch, HADOOP-8327.patch,
> HADOOP-8327.patch
>
>
> Distcp v2 (hadoop-tools/hadoop-distcp/...) and Distcp v1
> (hadoop-tools/hadoop-extras/...) are currently both built, and the resulting
> hadoop-distcp-x.jar and hadoop-extras-x.jar end up in the same class path
> directory. This causes some undeterministic problems, where v1 is launched
> when v2 is intended, or even v2 is launched, but may later fail on various
> nodes because of mismatch with v1.
> According to
> http://docs.oracle.com/javase/6/docs/technotes/tools/windows/classpath.html
> ("Understanding class path wildcards")
> "The order in which the JAR files in a directory are enumerated in the
> expanded class path is not specified and may vary from platform to platform
> and even from moment to moment on the same machine."
> Suggest distcpv1 be deprecated at this point, possibly by discontinuing build
> of distcpv1.
