mokai updated HBASE-29632:
--------------------------
    Description: 
ServerCall has rpc callback, it handles some logic while setting the response 
like conver pread scan to stream scan. The processing time is calculated before 
it, the time of open stream scanners is much more than processing time if the 
NameNode pressure is high.
