Anfernee Yongkun Gui updated THRIFT-2335:
-----------------------------------------
Attachment: Screenshot 2014-01-29 15.41.28.png
Left hand side is the python tornado client to python tornado server. Right
hand side the java client to python tornado server.
Left hand side has 00 00 00 3d at the beginning, but right hand side doesn't
have that.
Here I use binary protocol.
