Environment

Seen on 0.20.205.0, but may be an issue for other versions of hadoop-core (and probably other hadoop builds)

Description

hadoop-core fails to enforce dependency convergence, resulting in potential conflicts.

At the very least, there appears to be a direct dependency on

commons-httpclient:commons-httpclient:3.0.1

but a transitive dependency on

commons-httpclient:commons-httpclient:3.1

via

net.java.dev.jets3t:jets3t:0.7.1

See http://maven.apache.org/enforcer/enforcer-rules/dependencyConvergence.html for details on how to enforce dependency convergence in Maven.

Please enforce dependency convergence... it helps projects that depend on hadoop libraries build much more reliably and safely.
