Jonathan Gray commented on HBASE-1680:
--------------------------------------
@Clint, Are you trying to send custom Filter implementations over the wire as
well? Maybe I'm confused about what you're trying to do, could you describe?
We are looking at how to do dynamic filters in HBASE-1288.
> FilterList writable only works for HBaseObjectWritable defined types
