> # 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.
