-------------------------------------------

             Summary: Add HTrace distributed tracing for s3 and other alternative Hadoop FS
implementations
                 Key: COMDEV-191
                 URL: https://issues.apache.org/jira/browse/COMDEV-191
             Project: Community Development
          Issue Type: New Feature
            Reporter: Colin Patrick McCabe


The HTrace distributed tracing framework allows developers and system administrators to get
an end-to-end view of system performance, in a manner similar to XTrace or Dapper.  See http://htrace.incubator.apache.org/

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.  We should add HTrace distributed
tracing for s3 and other alternative Hadoop FS implementations.
