Description

• jar needs to be copied over
• are the file names being tracked being in the event currently ?
• copy to a standard location on HDFS (or local fs?) in destination when event is replicated
• modify the definition of the function in destination to point to this new location
• Limitation : all required jars need to be part of function definition
• Don't replicate temp functions
• handle jars specified in hive.aux.jars.path
