anishek updated HIVE-16591:
---------------------------
    Description: 
# We have to make sure that during incremental dump we dont allow functions to 
be copied if they have local filesystem "file://" resources.  -- depends how 
much system side work we want to do, We are going to explicitly provide a 
caveat for replicating functions where in, only functions created "using" 
clause will be replicated and the "using" clause prohibits creating functions 
with the local "file://"  resources and hence doing additional checks when 
doing repl dump might not be required. 

# We have to make sure that during the bootstrap / incremental dump we append 
the name node host + port  if functions are created without the fully qualified 
location of uri on hdfs, not sure how this would play for S3 or WASB filesystem.

# We have to copy the binaries of a function resource list on CREATE / DROP 
FUNCTION . The change management file system has to keep a copy of the binary 
when a DROP function is called, to provide capability of updating binary 
definition for existing functions along with DR. An example of list of steps is 
given in doc (ReplicateFunctions.pdf ) attached in  parent Issue.
