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

Hi, in our production cluster, huge msync is introduced to active. 

I think we still should continue two work:

(1) propagate state id as client need, avoid msync to namenode which is not 
used by client.

(2) share msync, reduce the mysnc operations.

[~simbadzina] How about my proposal?
