-----------------------------------

[~szetszwo] Hi, sorry for disturbing.  In ozone case, ozone client will call 
DataStreamOutputImpl#writeAsync many times to stream a big chunk, so only ozone 
client know how many times DataStreamOutputImpl#writeAsync has been called and 
when all the stream data has been replicated to all server. So should ozone 
client ask the leader to create a Raft transaction ?

Besides, DataStreamClientImpl can not connect to the leader, so do we need to 
use RaftClientImpl to ask the leader create a Raft transaction ?

> Create a transaction once the stream data is replicated to all servers
