Change subject: IMPALA-8842 part 1: (Hive3) Use 'engine' field in HMS stat API

Patch Set 7:

Commit Message:
PS7, Line 14: This change is Step 2 in a series of steps to coordinate the
            : introduction of HMS API changes to Hive3 and Impala. Step 4 is 
            : Impala related, it will be covered in IMPALA-8842 part 2.
            : The steps are as follows:
            : 1. Change in Hive3.
            : We push new APIs so Impala can use them. New APIs will simply 
call old
            : existing methods so there should not be any change of 
            : there. Since there were many incompatible changes, new APIs are 
            : method_name_V2.
            : 2. Change in Impala.
            : Push changes to use new methods *V2.
            : 3. Change in Hive3.
            : Push patch with complete functionality. *V2 methods contains the 
            : logic. The old existing methods are not used anymore by Impala at 
            : point, hence they can be removed. For every method_name_V2, I will
            : create a corresponding method method_name that calls the former 
            : 4. Change in Impala
            : Replace *V2 calls by *.
            : 5. Change in Hive3.
            : Remove *V2 methods from API
I am not sure why we need this in the commit message. The commit message should 
give details what the patch does and why. The coordination of patches between 
Hive and Impala can be done out-of-band and provides no value by recording the 
steps in the git commit message.

            :         </exclusion>
            :       </exclusions>
Is there a particular reason why this needs to be excluded for this patch?
