PS4, Line 16: This patch also introduces a new service pool for all query 
execution
            : control related RPCs in the future so that control commands from
            : coordinators aren't blocked by long-running DataStream services' 
RPCs.
> Thanks for the suggestion. I think it's fine to do it as a follow-up or par
Actually, after IMPALA-7585, we can achieve this by just setting a different 
username in the UserCredentials for different services. No change in Kudu code 
is needed.

Good idea. With 64-bit and 1 millisecond reporting interval, it will take about 
292471208 years for it to overflow.  With 32-bit values, it takes about 24 
days. I believe no legitimate query will run for 24 days but then I guess using 
64-bit provides the peace of mind.
