Yongjun Zhang commented on HADOOP-10250:
----------------------------------------
HI [~szetszwo], That's a very good question. I actually did try importing it
in my earlier attempt, it turned out to be not clean, basically
we need to import the whole package org.apache.maven.artifact.versioning
though we just need this single file. Plus it would create
hadoop dependency on maven (they have different version too). At that point, it
was decided that to make a copy of this file is a cleaner
and easier solution. I'm open for suggestions. Thanks.

> VersionUtil.compareVersions("1.0.0-beta-1", "1.0.0") returns 7 instead of
> negative number, which is wrong, because 1.0.0-beta-1 older than 1.0.0.
