Satish Mittal commented on OOZIE-1806:
--------------------------------------

Good point [~rohini]. I missed the fact that this patch would only work when sharelib is in default namenode. 

After the fix for OOZIE-1675, the method addToCache() was able to achieve the fine balance of a) working for both hadoop 0.20 and newer versions, b) handle scenarios when appPath points to non-default namenode, c) handle native binaries, jars with fragments etc. Later, this method call was replaced by explicit call to DistributedCache methods, thus causing the regression. [~puru] has also suggested on reviewboard to bring back addToCache, which I feel is the right thing.

I will upload a new patch that calls addToCache instead of explicit DistributedCache calls to restore the same state as OOZIE-1675.

> With oozie trunk, all java action type jobs are failing with hadoop 0.20.2 and earlier versions. This is a regression since oozie 4.0. The map tasks are failing with ClassNotFoundException for OozieLauncherInputFormat.EmptySplit class.
