---------------------------------------

Doc note:  This adds *hive.repl.replica.functions.root.dir* to HiveConf.java, and it's already documented in the wiki -- thanks, [~anishek]!

> # 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 namenode 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.
