Yongjun Zhang commented on HADOOP-10895:
----------------------------------------

HI [~tucu00],

Thanks a lot for your comment/suggestion. I did not see it earlier until now. I 
guess both of us were writing last comments at the same time. I think your 
suggestion of creating a static object for global setting would help here. I 
will work on addressing the comments from  you /Yi/Robert in next rev. 

Many thanks to Yi for some side discussion.
