Konstantin commented on LIVY-636:
---------------------------------
Exactly same exception when trying to add jar from HDFS through the "jars"
field; possibly for the same reason. Tried to add the main class to the jar (it
was meant to be library-only, so there was no main class presented initially) -
exception goes away, but imports from this jar are still impossible.
