Balu Vellanki commented on FALCON-2061:
---------------------------------------
The additional SLF4J bindings are coming because falcon-config.sh is adding
`hadoop classpath` to falcon client classpath. This was needed in past versions
of falcon because falcon-recipe was on the client side. Now that recipe is
renamed to extensions and moved to server side, we no longer need to add
`hadoop classpath` to falcon client classpath
Will provide a patch soon.
