stack commented on HBASE-7533:
------------------------------
Currently in RPC, there is an ExceptionMessage used to carry exceptions. It
has, as you'd expect, exception name and stack trace. What if we added opaque
Map, a repeatable PairByteBytes, to ExceptionMessage. On serialization, we'd
looks for a Dictionary marker Interface. If present, would serialize the
content. Ditto on deserialize. Would not be evolvable. You would have to
have a different key name if you wanted to change format. Its generic though.
