Steve Loughran commented on HADOOP-17790:
-----------------------------------------
I'd really like this to pick up and integrate with the work of the S3A
auditing, HADOOP-17511. This adds the code to hadoop-common to create a
referrer header containing call context operation (FS API call, paths,
principal), including job UUID which will span entire jobs (e.g. all spark
workers)
# Can the context use this and attach to requests
# is there a way for myself and others to get at the logs. I don't think I can
currently see the X-trace headers, can I?
