Colin Patrick McCabe commented on HDFS-9853:
--------------------------------------------
Thanks, Anu.
{code}
96 // A string that identifies this command, we generate Trace ID in
Ozone
97 // frontend and this allows us to trace that command all over ozone.
98 optional string traceID = 2;
{code}
HTrace trace IDs are 128-bit integers. I think we should avoid using a string
here since it is not as efficient as simply using two 64-bit numbers. I also
don't see why the response needs a trace ID, since the client knows the ID of
the request it sent.
