What is the rationale for having the hadoop JARs outside of the lib/
directory?
It would definitely simplify packaging configuration if they are under lib/
as well.
Any objection to it?
Thanks.

Eric,
Even if the JAR is in lib/ you could import/use that JAR only.
How would you use Hadoop JARs without its dependencies? Many things will
break unless you add the dependency JARs.
Granted, there are JARs that are used by Hadoop server side only
It is easier to write shell script to import jar files by directory instead of
explicitly reference to a few jars with specific versions.
The common use case is:
HBase needs to use hadoop jar files, but HBase depends on more recent version
of log4j. The construction of the class path would
