Maximilian Michels commented on FLINK-5234:
-------------------------------------------

I thought about always logging the classpath sources (Hadoop, Yarn, Hbase) in 
addition to listing all the classpath entries on debug.

Loading classes in this order: Flink, Hadoop, Yarn, Hbase

> Inform user about classpath configuration

> Our {{config.sh}} script constructs the classpath from a series of different 
> sources, i.e. Flink lib dir, Hadoop, Yarn, Hbase. Upon launching user jobs, 
> we should inform the user about the classpath which is used. This can avoid 
> hard to debug dependency collisions.
