Virag Kothari commented on OOZIE-1311:
--------------------------------------
If I understand correctly, now it will be mandatory to upload the sharelib to
hdfs as it has the launcher classes.
Before the sharelib had only jars for a specific action and it was optional to
upload the sharelib to hdfs. So this will add an extra deployment step, correct?
> Refactor action Main classes into sharelibs

> We should refactor {{PigMain}}, {{HiveMain}}, and {{SqoopMain}} classes into
> their respective sharelib so we can remove all of their dependencies from
> oozie-core. This will help prevent dependency issues in the future (e.g.
> different versions of antlr). These Main classes would then end up in the
> sharelib instead of the launcher jar. Their tests would also have to be
> moved to the sharelib, but not the ActionExecutors.
