Steve Loughran commented on HADOOP-13762:
-----------------------------------------
can you change thread names on the fly? What's the cost?
username comes with FS instance; we can include both in construction. Hadn't
thought about dynamic ops
> S3A: Set thread names with more specific information about the call.

> Running {{jstack}} on a hung process and reading the stack traces is a
> helpful way to determine exactly what code in the process is stuck. This
> would be even more helpful if we included more descriptive information about
> the specific file system method call.
