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

Hi [~fsk119],

     I have finished first version . the code is located in  
[https://github.com/xiangtao/flink/commit/6fe285044f1caee4d83165f0e5b76d61bbffe718
 
|https://github.com/xiangtao/flink/commit/6fe285044f1caee4d83165f0e5b76d61bbffe718]for
 temporary use.  You can review the design and the code and I will be very 
happy to hear your advices. 

    the main implement logic is : 
 # Add a method resetSessionProperty(String sessionId, String key)  in Executor 
interface
 # Add a method reset(String key) in SessionContext

     I wonder if I should add methods in Executor ?  because i can't get 
SessionContext or DefaultContext refrence in CliClient.
