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.
