Eric Yang commented on HADOOP-7615:
-----------------------------------

Owen recommended to put the jar files into 
$HADOOP_PREFIX/share/hadoop/$project/lib to reduce custom script to construct 
class path for contrib projects.  For capacity-scheduler and fair scheduler, 
the package path are clean and independent from each other, there shouldn't be 
any issue to have both on the class path.

> Binary layout does not put share/hadoop/contrib/*.jar into the class path

> For contrib projects, contrib jar files are not included in HADOOP_CLASSPATH 
> in the binary layout.  Several projects jar files should be copied to 
> $HADOOP_PREFIX/share/hadoop/lib for binary deployment.  The interesting jar 
> files to include in $HADOOP_PREFIX/share/hadoop/lib are: capacity-scheduler, 
> thriftfs, fairscheduler.
