Colin Patrick McCabe commented on HADOOP-12949:
-----------------------------------------------
Yeah, we certainly could use the UA header for this. That assumes that
Amazon's s3 implementation will start looking for this (which maybe they
will?). In the short term, the big win will be just connecting up the job
being run with the operations being done at the s3a level.

> Hi All,
> s3, GCS, WASB, and other cloud blob stores are becoming increasingly
> important in Hadoop. But we don't have distributed tracing for these yet. It
> would be interesting to add distributed tracing here. It would enable
> collecting really interesting data like probability distributions of PUT and
> GET requests to s3 and their impact on MR jobs, etc.
> I would like to implement this feature, Please shed some light on this
> Thanks,
> Madhawa
