Review request for Sqoop.
Bugs: SQOOP-1192
https://issues.apache.org/jira/browse/SQOOP-1192
Repository: sqoop-trunk
Description
-------
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.

Tested the new option with Oozie-Sqoop workflow to ensure it doesn't break
Sqoop library dependencies when launched by Oozie
