    Nit: please use the linux notation $SQOOP_HOME instead of the windows notation %SQOOP_HOME% (entire guide is written in a way to be compatible with linux, so it would be great to stay consistent).

> Now Sqoop will copy jar files in %SQOOP_HOME%\lib folder to the job cache every time a Sqoop job is launched. When Oozie launch a Sqoop job, this behavior can be optimized by add these jars in Oozie Sqoop sharelib. In this case, the jar files in share lib only needed be localized to each worker node once and reuse by all Sqoop job launched by Oozie. This can reduce massive disk I/O on worker node when using Sqoop by Oozie. To enable this, Sqoop need to have an option which enable the job to skip adding lib jars to the job cache. For now, this option should only be used by Oozie started Sqoop job. The patch attached introduce "--skip-dist-cache" option to enable this feature.
