Shuaishuai Nie updated SQOOP-1192:
----------------------------------
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.
> Add option "--skip-dist-cache" to allow Sqoop not copying jars in
> %SQOOP_HOME%\lib folder when launched by Oozie and use Oozie share lib
