Subject [jira] [Created] (HADOOP-8793) hadoop-core has dependencies on two different versions of commons-httpclient
Date Wed, 12 Sep 2012 21:01:08 GMT
Christopher Tubbs created HADOOP-8793:
-----------------------------------------

             Summary: hadoop-core has dependencies on two different versions of commons-httpclient
                 Key: HADOOP-8793
                 URL: https://issues.apache.org/jira/browse/HADOOP-8793
             Project: Hadoop Common
          Issue Type: Bug
          Components: build
    Affects Versions: 0.20.205.0
         Environment: Seen on 0.20.205.0, but may be an issue for other versions of hadoop-core
(and probably other hadoop builds)
            Reporter: Christopher Tubbs
            Priority: Critical


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

At the very least, there appears to be a direct dependency on
{code}commons-httpclient:commons-httpclient:3.0.1{code}
but a transitive dependency on
{code}commons-httpclient:commons-httpclient:3.1{code}
via
{code}net.java.dev.jets3t:jets3t:0.7.1{code}

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.
