stack updated HBASE-7533:
-------------------------
Attachment: rpc_spec3.txt
Redo to match spec. Let me do edit pass on spec. and run this through tests
then put up a patch on rb.
On patch, we used to pass in a fat pb object that was most of the header info
and then included the pb request param. Now we pass header and param
separately. Thats the spec.
Adds comments and some method and data member renaming to better match spec and
pb.
Because more of protocol in pb and because an rpc request is made of a pb
header and the already made pb param -- e.g. GetRequest, etc. -- and because we
pass exceptions as pb, etc., HBaseServer and HBaseClient has more pb in it now;
e.g. assembling the headers to make requests, undoing responses.
If error, the pb'd exception carries server/port if regionmoved and it is
marked do not retry if exception is such.
Remove dead code: ParallelCall, ParallelReturn
Added IPCUtil, FatalConnectionException
Moved internal classes out of HBaseServer and HRegionServer.
Getting the encoded datablocks the spec talks of in there is a todo as is
pb'ing the kv and work to cut down on buffer copies (the latter is a separate
issue).
