-----------------------------------------------
Hi [~madhawa], great idea! I think the first thing to do is to read a bit
about how to set up HTrace. See
http://blog.cloudera.com/blog/2015/12/new-in-cloudera-labs-apache-htrace-incubating/
If you can get a working setup for HTrace-on-HDFS, it will help for adding
tracing to other projects such as the s3a connector.

> 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
