java.lang.Objectorg.apache.hadoop.hbase.ipc.HBaseRPC
public class HBaseRPC
A simple RPC mechanism. This is a local hbase copy of the hadoop RPC so we can do things like address HADOOP-414 for hbase-only and try other hbase-specific optimizations like using our own version of ObjectWritable. Class has been renamed to avoid confusing it w/ hadoop versions.
A protocol is a Java interface. All parameters and return types must be one of:
boolean
, byte
,
char
, short
, int
, long
,
float
, double
, or void
; orString
; orWritable
; or
